Limestack Mountain

Limestack Mountain is a 6,250-foot peak in Alaska’s central Brooks Range within Gates of the Arctic National Park, with the continental divide running along its northern edge. Bob Marshall, an early European American explorer and mapper of the Brooks Range, named it after seeing its upper thousand feet as a gray stack of limestone while climbing through boulders and steep scree. He then reached the summit in the first recorded ascent. The mountain is distinguished by its massive limestone cliffs, compared to Yosemite, and by its prominence as the highest point in a rugged cluster of peaks, making it both a dramatic geologic landmark and part of Arctic Alaska’s early exploration history.
