Bodies of three mountaineers found in Canada

The bodies of three world-renowned professional mountaineers -- two Austrians and an American -- were found Sunday after they went missing during an avalanche on a western Canadian summit, the national parks agency said.

American Jess Roskelley, 36, and Hansjorg Auer, 35, and David Lama, 28, of Austria went missing late Tuesday at Banff National Park. Authorities launched an aerial search the next day.

The three men were attempting to climb the east face of Howse Pass, an isolated and highly difficult route. They were part of a team of experienced athletes sponsored by American outdoor equipment firm The North Face.

"Parks Canada extends our sincere condolences to their families, friends and loved ones," the agency said in a statement. "We would also like to acknowledge the impact that this has had on the tight-knit, local and international climbing communities. Our thoughts are with families, friends and all those who have been affected by this tragic incident."
