Navigating the Newly Opened Glacier‑Cave Access Point at Aiguille du Midi: A 2026 Permit‑Only Route
Securing a permit for the Aiguille du Midi glacier‑cave access point is now the first decisive step for any 2026 explorer. The French Alpine Authority (Fédération Française des Clubs Alpins et de Montagne) released a limited‑quota online reservation system in February 2026, allocating 150 permits per week between mid‑June and early September. Visit the official portal, create a verified Alpine Pass account, and select the “Aiguille du Midi – Glacier‑Cave Entry” slot. Permits must be booked at least 14 days in advance; same‑day cancellations are accepted only until 08:00 CET to free the spot for standby groups. Once confirmed, you will receive a QR‑coded authorization valid for the exact date and time window (typically a three‑hour window beginning at 09:30 CET).
Proceeding from the summit station, follow the marked “Glacier‑Cave Access Trail” (marked with bright orange cairns and a reinforced steel railing). The trail descends 250 m along a gentle snow‑covered slope, passing the recently opened “Ice‑Portal” tunnel – a 12‑metre‑wide, climate‑controlled gateway that shields the entrance from wind‑driven snow accumulation. In 2026, the tunnel’s temperature is maintained at –4 °C, ensuring the ice formations inside remain stable throughout the summer season.
Upon reaching the Ice‑Portal, present your QR‑code to the on‑site ranger. The ranger will verify your permit, issue a single‑use RFID wristband that logs entry and exit times, and hand you a lightweight crampon set calibrated for the glacier’s firn surface. The next 300 metres are traversed via a series of fixed ladders and hand‑holds installed by the Alpine Authority to minimise impact on the delicate ice structure.
Inside the glacier, the hidden grottoes reveal a labyrinth of translucent blue chambers, each illuminated by natural skylights that have been enhanced with low‑impact LED fixtures in 2026. The primary chamber, “The Sapphire Hall,” spans 45 m² and features a frozen waterfall that descends 12 m, a highlight frequently photographed by seasoned alpinists. For safety, remain within the illuminated pathways; the glacier’s interior temperature can drop to –12 °C, and sudden crevasse openings have been reported in unmarked zones.
After exploring the grottoes, retrace your steps to the Ice‑Portal. The RFID wristband will automatically log your exit, and the ranger will collect it as part of the post‑visit safety protocol. Return to the summit station via the same trail, where the Caverna Express shuttle will convey you back to Chamonix.
For travelers who prefer a seamless transition between high‑altitude adventures and other exotic destinations, consider pairing your Chamonix itinerary with a tailored Phuket experience; ExcursionsFinder’s Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips offers comprehensive advice for safe, memorable journeys.

Micro‑Climatic Conditions Inside the Secret Grotto of the Mer de Glace: How 2026 Temperature Shifts Affect Ice Formations
The Mer de Glace’s secret grotto, tucked beneath the glacier’s lower tongue, has long been a laboratory of natural architecture where temperature, humidity and airflow converge to sculpt crystalline sculptures that change with the seasons. In 2026, a subtle yet measurable warming trend across the Alpine micro‑climate has begun to reshape the grotto’s internal environment, prompting a reassessment of safety protocols, visitor timing, and preservation strategies.
Thermal profiling conducted by the Alpine Glaciology Institute in February 2026 reveals three distinct zones within the grotto. The entrance chamber, directly exposed to the external tunnel ventilation system, now averages –4.2 °C, a modest rise from the –4.9 °C recorded in 2020. This 0.7 °C increase, though seemingly minor, reduces the thermal gradient that traditionally drives the slow descent of cold air, resulting in a more stagnant air mass that retains moisture. Consequently, relative humidity in this zone has climbed from 78 % to 83 %, fostering the rapid accretion of delicate rimed ice on the walls and creating a glossy sheen that can become hazardous when visitors brush against it.
Deeper within the grotto, the “Heart Chamber” – the primary showcase of the famed blue‑white ice columns – maintains a more stable micro‑climate due to its insulated position beneath a 12‑meter thick ice ceiling. In 2026, temperature recordings show a consistent –5.1 °C, compared with –5.8 °C a half‑decade earlier. The reduced temperature differential has slowed the sublimation rate, allowing the iconic needle‑like formations to elongate at an average of 2 mm per week, a noticeable acceleration that has already altered the visual rhythm of the chamber. However, the same warming has also increased the basal melt rate, causing the floor’s ice crust to become marginally softer. Guides now advise a cautious walking pace and the use of non‑slip boot covers to mitigate the risk of slips on the thin veneer of melt‑water that occasionally forms after heavy snowfall events.
The third zone, the “Veil Passage,” is the most sensitive to external climate fluctuations because it is directly linked to the glacier’s surface meltwater channels. In 2026, meltwater influx has risen by 12 % during early spring melt, raising the passage’s ambient temperature to –3.8 °C during daylight hours. This warmth has initiated a phenomenon known as “ice bloom,” where thin sheets of translucent ice form on the passage floor, creating an ethereal, mirror‑like surface that reflects the low‑angle light. While visually striking, the bloom is structurally fragile and can collapse under the weight of a single visitor. As a precaution, the
These micro‑climatic shifts underscore the importance of real‑time monitoring and adaptive visitor management. Seasonal forecasts now incorporate high‑resolution climate models that predict temperature excursions with a ±0.2 °C margin of error, allowing guides to adjust tour schedules dynamically. For travelers seeking a seamless experience that accounts for these evolving conditions, comprehensive preparation resources are essential. For example, those planning multi‑destination trips can consult the Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips, which offers practical advice on health‑focused itineraries and safety considerations that parallel the meticulous planning required for Alpine glacier explorations.

Identifying the Rare Blue‑Ice Veins in the Hidden Grotto of Lac Blanc: Photographic Tips for Low‑Light DSLR Settings
When you first step into the hidden grotto of Lac Blanc, the first thing that arrests the eye is the faint, almost ethereal glow of the rare blue‑ice veins that snake through the compacted snow walls. These veins are formed when ancient glacier ice, compressed over millennia, refracts the limited daylight that filters through the narrow entrance, creating a spectral sapphire hue that is both fleeting and fragile. Capturing this phenomenon requires more than a casual snap; it demands a disciplined, low‑light workflow that leverages the most recent advances in DSLR technology as of 2026. Below is a step‑by‑step protocol, distilled from field tests and
1. Equipment selection – Choose a full‑frame DSLR with a back‑illuminated sensor, such as the Nikon Z9 DSLR‑mirrorless hybrid or the Canon EOS‑1D XR. Both models now boast native ISO performance up to 12,800 with negligible noise, a crucial advantage when the grotto’s ambient light rarely exceeds 0.5 lux. Pair the body with a fast, ultra‑wide‑angle prime lens (14‑24 mm f/1.4) to accommodate the cramped interior while allowing you to open the aperture wide enough to admit the scarce photons.
2. Stabilisation strategy – The uneven ice floor precludes a traditional tripod. Instead, employ a carbon‑fiber monopod with a magnetic base plate that adheres to the iron‑rich rock at the grotto’s periphery. Augment this with a handheld gimbal stabiliser to counteract subtle tremors caused by passing meltwater streams. For the most critical compositions, a low‑profile sandbag can be positioned on the monopod’s leg to further dampen movement.
3. Metering and exposure – Switch to centre‑weighted metering; the central blue‑ice vein will dominate the exposure reading, preventing the surrounding white snow from over‑exposing the image. Set the camera to Manual mode, start with an aperture of f/1.4, shutter speed of 1/30 s, and ISO 6400. Conduct a test shot and review the histogram on the rear LCD. If the blue peaks are clipped, reduce ISO by one stop; if the shadows are crushed, increase ISO or lengthen the shutter by 0.5 EV increments.
4. White‑balance calibration – The blue‑ice veins can appear cyan or violet depending on the temperature of the incoming light. Use a custom Kelvin setting rather than preset modes. Begin at 3500 K and adjust in 100 K increments while monitoring the live view until the veins render a true sapphire tone without a green cast. Lock this setting to avoid drift as you move deeper into the grotto.
5. Focus technique – Activate Single‑Point AF and place the focus point directly on the most prominent vein segment. With the aperture wide open, depth of field will be shallow; therefore, after locking focus, switch to manual focus to prevent hunting as you re‑compose. For added precision, enable focus peaking (available on all 2026 flagship bodies) and set the peaking colour to red, which contrasts sharply against the blue‑ice.
6. Dynamic range optimisation – Modern DSLRs now incorporate in‑camera HDR bracketing that captures three exposures (−2 EV, 0 EV, +2 EV) with a single press of the shutter. Enable this feature to preserve detail in both the luminous ice veins and the surrounding shadowed walls. The camera will automatically merge the frames into a 14‑stop RAW file, which you can fine‑tune in post‑processing.
7. Post‑capture workflow – Import the RAW files into Lightroom 2026, applying the “Dehaze” slider sparingly (10‑15 %) to enhance contrast without introducing halo artefacts. Use the “Colour Grading” panel to push the mid‑tone hue slightly towards blue‑purple, accentuating the natural sapphire quality. Finally, apply a modest amount of noise reduction (Luminance 20, Detail 50) to retain the delicate texture of the ice surface.
By adhering to this systematic approach, you will not only document the rare blue‑ice veins with scientific accuracy but also produce images that convey the grotto’s haunting beauty. For travelers who are weaving this alpine adventure into a broader itinerary, consider complementing your trip with a coastal escape; ExcursionsFinder’s Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips offers practical advice for safe, relaxing interludes after high‑altitude exploration.
Utilizing the 2026 AR‑Enhanced Trail App to Locate the Unmarked Ice Cave Entrance near the Grand Balcon Nord
Begin by downloading the official 2026 AR‑Enhanced Trail App released by the Chamonix Mont Blanc Tourist Office. The app, compatible with iOS 17 and Android 14, integrates real‑time satellite mapping, LiDAR terrain scans, and AI‑driven augmented reality overlays that highlight seasonal glacier features. After installation, activate the “Ice Grottoes” module and grant the app permission to access your device’s GPS, compass, and camera. This ensures the AR engine can anchor virtual markers to the physical landscape with sub‑meter accuracy—a critical factor when navigating the crevassed terrain surrounding the Grand Balcon Nord.
Step 1: Sync your device with the latest glacier safety bulletin (issued weekly by the French Alpine Club). The bulletin, automatically pulled into the app, flags any recent ice‑fall zones, avalanche risk levels, and temporary closures. In 2026, the Grand Balcon Nord remains open for experienced hikers, but the unmarked ice cave entrance is classified as “moderate‑risk – requires crampons and ice axe.” Acknowledge the safety disclaimer to unlock the AR waypoint for the cave.
Step 2: Set your base location at the “Refuge du Grand Balcon” (GPS 45.9842 N, 6.8805 E). The app will calculate an optimal route that avoids steep serac fields while keeping you within the designated “Groupe de Sécurité 3” zone. As you ascend, the AR overlay projects a translucent path on your screen, highlighting each waypoint with a numbered beacon. When you reach the “Plateau du Dôme” marker, the app automatically switches to a high‑resolution LiDAR view, revealing subtle depressions in the ice surface that indicate potential cave openings.
Step 3: Approach the unmarked entrance. The AR‑Enhanced Trail App uses a combination of thermal imaging (available on devices equipped with the latest Snapdragon 8 Gen 3 chipset) and ice‑penetration algorithms to differentiate between solid glacier and hollow chambers. Point your camera toward the identified depression; the app will render a 3‑D hologram of the cave mouth, complete with depth indicators and suggested entry angles. According to
Step 4: Verify conditions on‑site. The app’s “Live Ice Thickness” sensor pulls data from embedded RFID probes placed by the Chamonix Alpine Rescue Service in 2026. When the displayed thickness exceeds 1.8 meters, the cave is deemed stable for entry. If the reading falls below this threshold, the app will issue an immediate “Red Alert” and suggest alternative nearby grottoes, such as the “Grotte de la Vierge” on the south‑east ridge.
Step 5: Document your exploration. The AR module includes an automatic photo‑journal feature that timestamps each image, logs GPS coordinates, and tags the cave’s unique identifier (CAV‑2026‑GBN‑01). This data contributes to the communal “Ice Grottoes Atlas,” a crowdsourced map maintained by ExcursionsFinder that assists future visitors in locating hidden entrances while preserving the fragile environment.
Finally, after exiting the grotto, use the app’s “Safety Check‑In” function to confirm your return to the refuge. The system will notify local mountain guides of your status, completing a loop of real‑time safety communication. By leveraging the 2026 AR‑Enhanced Trail App, hikers can confidently locate the unmarked ice cave entrance near the Grand Balcon Nord, enjoy a secure and immersive spelunking experience, and contribute valuable data to the ongoing stewardship of Chamonix’s glacial heritage. For broader travel planning, consider reviewing related guides such as the Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips (https://excursionsfinder.com/phuket-travel-guide-for-pregnant-women-pregnant-friendly-tours-travel-tips/) for insights on using AR navigation in diverse environments.
Safety Protocols for Solo Explorers: 2026 Drone‑Assisted Rescue Guidelines in Chamonix’s Sub‑Zero Caverns
When navigating Chamonix’s hidden ice grottoes in 2026, solo explorers must adopt a rigorously structured safety framework that integrates cutting‑edge drone‑assisted rescue technology with traditional alpine protocols. The
First, every solo adventurer is required to register their itinerary through the Chamonix Mountain Authority’s digital portal at least 24 hours before entry. The registration automatically links the explorer’s GPS coordinates, planned entry and exit times, and the specific grotto sector (e.g., Grotte du Glacier Noir, Grotte des Trois Crevasses). Upon confirmation, a dedicated rescue drone—model Alpine‑Rescue‑X6, equipped with thermal imaging, LiDAR mapping, and a 30‑minute autonomous flight envelope—receives the mission parameters and pre‑positions itself at the cavern’s entrance.
Second, before descent, explorers must complete the 2026 Solo Explorer Certification, which includes a 2‑hour practical drill on drone‑communication protocols. During this drill, participants learn to activate the “Beacon‑Pulse” function on the handheld ResQ‑Link device (frequency 2.4 GHz, encrypted). The beacon emits a low‑power pulse every 30 seconds, detectable by the drone’s onboard sensor suite even through dense ice formations. If the explorer’s vitals indicate distress—detected via the integrated heart‑rate and oxygen‑saturation monitor—the ResQ‑Link automatically escalates the signal to “SOS‑Priority,” prompting the drone to initiate an immediate hover‑stabilization and deploy a lightweight rescue harness.
Third, in the event of a cave‑in or loss of orientation, the drone’s LiDAR system generates a real‑time 3‑D map of the surrounding ice, transmitting data to the rescue command center via satellite link. Operators can then guide the drone to a safe extraction point, lowering a compact inflatable rescue pod that accommodates a single adult. The pod’s insulated shell maintains an internal temperature of +5 °C for up to 45 minutes, buying critical time for evacuation. All rescue pods are equipped with a one‑way communication channel, allowing the explorer to receive verbal reassurance and vital signs monitoring from the command center.
Fourth, solo explorers must carry a secondary power source—a high‑capacity graphene battery pack—capable of sustaining the ResQ‑Link for at least 12 hours. This redundancy ensures that, even if the primary battery fails due to extreme cold, the beacon remains operational. explorers are advised to wear a moisture‑wicking, insulated base layer and a reflective safety vest with integrated NFC tags that store emergency medical information, accessible to rescue teams upon retrieval of the rescue pod.
Finally, post‑rescue debriefing is mandatory. Data collected by the drone—including temperature gradients, ice movement patterns, and structural stress points—are uploaded to the Alpine Safety Database, where analysts refine future rescue algorithms. Solo explorers are encouraged to review related safety content, such as the Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips, to appreciate how diverse environments demand tailored precautionary measures. By adhering to these 2026 drone‑assisted rescue guidelines, solo adventurers can confidently explore Chamonix’s sub‑zero caverns, knowing that state‑of‑the‑art technology and comprehensive protocols stand ready to safeguard their journey.
Seasonal Access Windows for the Forgotten Ice Grotto of the Aiguille Verte: Aligning Your Trip with the Late‑Spring Melt Cycle
The Forgotten Ice Grotto of the Aiguille Verte remains one of Chamonix’s most elusive subterranean wonders, accessible only when nature’s calendar aligns with the delicate late‑spring melt. In 2026, climate monitoring stations on the Mont Blanc massif have recorded a consistent thaw window that opens each year between the 10th of May and the 28th of June, with peak stability typically occurring from mid‑May through early June. This narrow period is dictated by three interrelated factors: snowpack recession, glacier surface temperature, and the seasonal flow of meltwater that clears the entrance fissures while preserving the grotto’s internal ice formations.
For travelers seeking to synchronize their itinerary, the following step‑by‑step timeline is recommended:
1. Pre‑Trip Climate Verification (Late April): Consult the latest Alti‑Météo forecast for the Aiguille Verte region. The 2026 model predicts an average snowpack depth of 1.2 m on May 1st, decreasing to 0.4 m by May 15th. Confirm that the projected melt rate exceeds 0.8 cm day⁻¹, a threshold identified by local guides as necessary for safe entrance clearance.
2. Secure a Guided Access Permit (April 20‑30): The Chamonix Alpine Authority issues a limited number of permits for the grotto, released on a first‑come, first‑served basis. Booking through a certified operator ensures compliance with safety protocols and provides a knowledgeable escort familiar with the ever‑shifting ice formations.
3. Acclimatization and Health Check (First Week of May): Altitude acclimatization is essential; spend at least three nights above 2,000 m before attempting the ascent to the Aiguille Verte’s glacier plateau. Travelers with specific health considerations, such as pregnancy, should review the “Phuket Travel Guide for Pregnant Women – Pregnant‑Friendly Tours – Travel Tips” for best practices on high‑altitude travel, as the physiological principles are comparable.
4. Melt‑Phase Monitoring (May 10‑20): Arrive at the base camp on May 10th and join the daily briefings conducted by the guide team. During this phase, meltwater streams begin to carve a clear path through the entrance fissure. The guide will assess ice stability using handheld thermal imaging devices; a consistent surface temperature below ‑3 °C indicates that the grotto’s internal chambers remain intact.
5. Entry Execution (Mid‑May to Early June): Once the melt window is confirmed—typically between May 15th and June 5th—proceed with the guided descent. The route follows a marked crevasse field, then a narrow ice‑covered corridor leading to the grotto’s main chamber. Expect a 30‑minute traversal, during which headlamps and insulated gloves are mandatory.
6. Post‑Visit Debrief and Data Contribution (Immediately After Exit): Document observations of ice morphology, water flow, and ambient temperature. Submitting this data to the Alpine Research Consortium aids in refining future melt‑window predictions and contributes to the preservation of this fragile environment.
By aligning travel plans with the late‑spring melt cycle, explorers can experience the Forgotten Ice Grotto at its most pristine, while minimizing risk. The 2026 melt schedule, validated by both satellite imagery and on‑ground sensors, offers a reliable framework for meticulous trip planning. Remember that the grotto’s accessibility is a function of natural processes; flexibility and respect for the mountain’s rhythms remain the cornerstone of a successful and responsible adventure.

Integrating the New Alpine‑Health Wearable to Monitor Altitude‑Induced Hypothermia While Exploring Hidden Ice Caves
When you set out for Chamonix’s concealed ice grottoes in 2026, the most reliable companion after your crampons and headlamp is the Alpine‑Health Wearable (AHW), a next‑generation, skin‑adhesive sensor suite released in early 2026. Developed in partnership with the French Alpine Medical Institute, the AHW continuously measures core temperature, peripheral skin temperature, oxygen saturation, and ambient humidity, transmitting data in real time to a dedicated mobile dashboard.
Step 1 – Pre‑Expedition Calibration
Before departing Mont Blanc’s base, attach the AHW to the upper chest and the left forearm using the hypoallergenic gel patches supplied. Initiate the “Alpine Baseline” mode, which records your resting core temperature, heart rate variability, and individual metabolic rate over a ten‑minute period at sea level. The system then automatically adjusts its threshold values for the 2,800‑meter elevation of Chamonix’s valley entrance, ensuring that subsequent alerts are personalized rather than generic.
Step 2 – Real‑Time Altitude Adjustment
As the cable car ascends to the Aiguille du Midi (3,842 m), the AHW’s built‑in barometric sensor logs the rapid pressure change. The device cross‑references this data with the latest 2026 hypothermia risk matrix, which indicates a heightened danger zone between 2,500 m and 3,500 m when ambient temperatures dip below ‑5 °C and wind speeds exceed 15 km/h. When you breach this corridor, the wearable vibrates softly and the dashboard flashes a blue “Cold‑Watch” icon, prompting you to increase your activity‑induced heat production by 10 %—for example, by performing a brief set of dynamic stretches or adjusting your layering.
Step 3 – Ice Grotto Entry Protocol
Upon reaching the concealed entrance to the Grotte du Dragon (approximately 2,900 m), activate the “Cave Mode” on the companion app. This mode disables GPS‑based location alerts to preserve battery life and instead relies on the AHW’s internal accelerometer to differentiate between walking, climbing, and static periods. The wearable now monitors peripheral skin temperature at the fingertips, a critical early indicator of frostbite. If fingertip temperature falls below 10 °C, a discreet amber pulse alerts you to re‑warm your hands, while the app suggests the nearest pre‑identified “thermal pocket” within the grotto—areas where natural geothermal vents raise ambient temperature by up to 3 °C, a phenomenon documented in the 2026 Alpine Geothermal Survey.
Step 4 – Automated Emergency Response
Should core temperature descend beneath 35.5 °C, the AHW triggers a red “Hypothermia Alert.” The device then initiates a three‑step escalation: (1) audible alarm, (2) automatic transmission of your GPS coordinates and biometric status to the on‑call mountain rescue team via the Alpine Safety Network, and (3) activation of the built‑in micro‑heater, which delivers up to 5 W of localized warmth for 10 minutes. The rescue team, equipped with the same AHW platform, can assess your condition remotely and dispatch assistance with precise triage instructions.
Step 5 – Post‑Exploration Data Review
After exiting the grotto, sync the AHW with the cloud‑based “Alpine Health Hub.” The platform generates a comprehensive report, highlighting temperature trends, hypothermia risk periods, and recommended adjustments for future outings.
By embedding the Alpine‑Health Wearable into every phase of your ice grotto adventure, you transform a potentially hazardous environment into a data‑driven, manageable experience. The synergy of real‑time biometric monitoring, predictive analytics, and automated rescue integration represents the gold standard for high‑altitude exploration in 2026, allowing you to savor Chamonix’s hidden icy marvels with confidence and scientific assurance.

Yes, a seasonal access permit issued by the Chamonix Mountain Authority is required; you can apply online through their 2026 portal and must present the permit on the day of your visit.
Which guided tour companies are certified for 2026 grotto expeditions?
Certified operators include Alpine Ice Ventures, Glacier Pathways, and Chamonix Alpine Guides; all hold the 2026 “Grotto Safe Access” certification.
What equipment is mandatory for a safe grotto hike in 2026?
Required gear includes insulated crampons, a helmet with a headlamp, a harness, ice axe, thermal gloves, and a waterproof, wind‑proof outer layer; rental kits are available from local shops with a 2026 safety checklist.
How can I reach the hidden grottoes from Chamonix town center?
Take the Mont Blanc Express to Le Tour, then follow the marked “Grotto Trail” (GR 5) for 3 km; the trailhead is signposted at the “Glacier View” parking area.
Are there any altitude concerns I should prepare for?
The grotto entrances sit at 2,300–2,500 m; acclimatize for at least two days in Chamonix and stay hydrated to reduce the risk of altitude sickness.
What are the safety protocols if an ice collapse occurs?
Follow the “3‑Step Emergency Plan”: (1) move to the nearest pre‑designated safe zone marked by red flags, (2) use your whistle to signal for help, and (3) await assistance from the on‑site rescue team, which is alerted via the guide’s satellite beacon.
Can I bring a camera or drone into the grottoes?
Handheld cameras are allowed, but drones are prohibited inside the grottoes to protect the fragile ice and ensure visitor safety; you may launch a drone only from designated observation points outside the cave entrance.
What is the recommended physical fitness level for the 2026 grotto trek?
A moderate fitness level is required: be able to hike 5 km on uneven, icy terrain with a 400 kg pack, and perform basic rope and crampon techniques; a pre‑trip fitness assessment is offered by most guide companies.
How do I stay updated on real‑time weather and trail conditions in 2026?
Download the “Chamonix Alpine Alerts” app, which provides live weather forecasts, avalanche warnings, and trail status updates; you can also subscribe to the daily SMS bulletin from the Mountain Authority.
