Mountain Rescue Aspen, with the assistance of the Pitkin County Sheriff's Office and St. Mary's Careflight, rescued a hiker from the Snowmass Creek Trail Thursday afternoon.

The Sheriff's Office received a call around 3 p.m. from the companion of a hiker whose health had been deteriorating “over the past couple of days in the backcountry,” according to a press release. The companion was concerned that the hiker was falling victim to high altitude pulmonary edema and would be unable to leave the area under his own power. The reporting party left his friend a few miles below Snowmass Lake and hiked out to get help.

In response, Mountain Rescue Aspen sent a 17-member foot team to the area with medical supplies. According to the release, after examining the hiker, the team called in a helicopter from St. Mary's Careflight for medical evacuation.

The helicopter successfully extracted the hiker from the field and all members of Mountain Rescue Aspen were out of the field by 6:35 p.m.

Mountain Rescue Aspen would like to remind backcountry users to listen to their bodies, and take failing health conditions seriously. Emergency medical resources may not be immediately available, and backcountry rescues are inherently dangerous for all involved.
