Zebulon Pike
In early November 1806, Pike and his team sighted and tried to climb to the summit of the peak later named after him (Pikes Peak). They made it as far as Mt. Rosa, located southeast of Pikes Peak, before giving up the ascent in waist-deep snow. They had already gone almost two days without food.
Longs Peak
The record number of ascents to the summit of Longs Peak is 428, by Jim Detterline. Jim was a rescue Ranger in Rocky Mountain National Park. On October 23, 2016, he died in an accident while solo climbing.
Jim rescued over 1,000 people in the mountains of Rocky Mountain National Park and he received the U.S. Interior Department's Valor Award. He also, earned the title,"Mr. Longs Peak". http://www.alpinist.com/doc/web16f/newswire-detterline-obit
