AMGA Alpine Guide Heidi Kloos, 41, died in an avalanche on Tuesday, March 30, 2010. It is believed that Kloos was ascending on skis to a remote ice climb on Mt. Baldy in the Cimarron Mountains east of Ridgway, Colorado, when a slide released from above the cliff, burying Kloos beneath several feet of snow. Wednesday morning, friends alerted Search and Rescue, who found her dog, her backpack and one ski at the site. The body was recovered on the afternoon of Thursday, April 1.
 
Heidi had been guiding and climbing, both rock and mountaineering routes around the world for over a decade.  One of the select few female, AMGA Certified Alpine Guides, Heidi was based in Ridgway, Colorado.  Heidi guided full time on rock, ice and big alpine routes and was a Senior Guide with Mountain Trip.  She guided 10 Denali trips as well as expeditions to South America and Nepal. 

Most recently, Kloos had been inspired by her work guiding disabled veterans on the slopes of Denali. The program is run by the Telluride Adaptive Sports Program in conjunction with Mountain Trip, for whom Kloos was a regular guide; she had been looking forward to returning to Denali with TASP this summer.

When not in the mountains, she helped run an Alpaca ranch, caring for a large herd of valuable alpacas as well as the assorted cows, chickens, goats, turkey and two camels.
