PITKIN COUNTY, CO — On the morning of June 25, 2025, at approximately 6:50 a.m., Pitkin County Regional Emergency Dispatch received an urgent SOS from Snowmass Lake, situated at 10,800 feet elevation in the Maroon Bells–Snowmass Wilderness. A seventeen‑year‑old hiker exhibiting signs of advanced altitude illness—shortness of breath, vomiting, and foaming at the mouth—was in urgent need of rescue.
Mountain Rescue Aspen, equipped with communication via Garmin inReach, confirmed the youth’s asthma condition and evolving symptoms. Recognizing the severity, MRA quickly escalated the situation through the Colorado Search and Rescue Association (CSAR).
Simultaneously, a Colorado Army National Guard Blackhawk helicopter from HAATS in Gypsum, already operating at Aspen’s Sardy Field on a Capitol Peak mission, was redirected. Upon reaching Snowmass Lake, a specialized MRA hoist-rescue technician performed a field medical evaluation, then secured the teenager via hoist into the Blackhawk.
From there, the patient was airlifted back to Sardy Field, where Aspen Ambulance personnel transferred them to Aspen Valley Health – Hospital and Medical Center for further treatment. The operation concluded with all rescue personnel out of the wilderness by 11 a.m., marking a successful multi-agency life-saving effort.

Snowmass Lake is an ambitious 8.5-mile hike commonly attempted by experienced outdoor enthusiasts. This rescue underscores how even fit, youthful hikers can rapidly deteriorate at high altitudes. The seamless coordination—911 dispatch, satellite communication, ground SAR, helicopter, and medical transport—reveals advanced preparedness and interagency cooperation.
According to the Wilderness Medical Society, altitude sickness can escalate swiftly above 9,000 feet, especially when hikers ascend faster than their bodies can acclimate. Recognizing symptoms—headache, nausea, vomiting, shortness of breath—is vital.
Lessons Learned & Safety Tips
Pre-acclimatize: Spend a day or two at intermediate elevations (8,000–10,000 ft) before pushing higher.
Travel slow & hydrate: Ascend gradually, monitor exertion and hydration.
Know the signs: Vomiting, breathing issues, persistent headaches, or confusion can signal serious altitude illness.
Communication matters: Devices like Garmin inReach allow two-way messaging where cell service fails.
Emergency readiness: Carry whistle, signal mirror, sunscreen, layers, and first aid. A CPW guide to altitude sickness offers more prevention tips.
