Nature
Dillon Mountain is a 4,820-foot summit in Alaska’s Philip Smith Mountains of the Brooks Range, north of the Arctic Circle near the Dalton Highway and the confluence of the Bettles and Dietrich rivers. Though modest in elevation by major range standards, it dominates the landscape through its immense west face, where Skajit limestone rises nearly 3,400 feet above the valley. The mountain was named for geologist John Thomas Dillon of the Alaska Division of Geological and Geophysical Surveys, who mapped the southern Brooks Range mineral belt and died in a 1987 airplane crash in the Brooks Range while returning from fieldwork with his father, Stephen Patrick Dillon.
