One Alaska geologist’s explanation: With a lack of the freeze-thaw process that other mountains experience, Denali doesn’t erode as quickly as others.
Kara Haeussler skis back to an airstrip on Kahiltna Glacier in 2014 with Denali in the far background and the Kahiltna Peaks in the foreground right.
Haeussler — pretty tall himself at 6-foot-6 — has slept on and analyzed mountain ranges all over Alaska during the past 30 years as a professional with the U.S. Geological Survey in Anchorage. During the 2023 Fall Meeting of the American Geophysical Union in San Francisco last December, Haeussler explained why he believes Denali stands head and shoulders above neighboring peaks.
One important journey for him in formulating an answer was the few weeks he spent near Denali with his daughter Kara and colleague/friend Richard Lease 10 summers ago. Peter Haeussler emerged from this hole in the Kahiltna Glacier after falling into a crevasse during a rock-gathering mission in 2014.
After he emerged, Haeussler ate a snack and then used his ice ax to chop out a rock sample for his studies.
