2011 Map of Jack Mountain

About this map

Jack Mountain stands as the central landmark of this high-elevation terrain, anchored by the significant ice mass of the Nohokomeen Glacier on its northern slopes. The landscape is defined by a complex drainage system where the North Fork Devils Creek and Devils Creek converge, eventually feeding southward toward Jerry Lakes. This area of Whatcom County remains largely undeveloped, characterized by isolated backcountry locations such as Bear Skull Shelter near Dry Creek Pass. The map details the transition from high peaks like Devils Dome and Spratt Mountain to the deep-cut valleys of Grizzly Creek and Middle Creek. This topographic record provides a look at the glacial and hydrological patterns of the North Cascades before contemporary shifts in ice coverage significantly altered these alpine features.
