Annual Mountaineering Summaries
Each year, the staff at the Walter Harper Talkeetna Ranger Station compiles a summary of mountaineering activities in Denali National Park and Preserve. The 2013 Annual Mountaineering Summary is now available, and includes our yearly rescue and medical summaries, a statistical review, a rundown of notable ascents, and other articles about our mountaineering program and the people who help make it all happen.
Below are links to the summaries dating back to 1979.
