2002 Map of Jack Mountain

About this map

Jack Mountain dominates the southern landscape of this Cascades survey, anchoring a high-altitude terrain defined by the Nohokomeen Glacier and deep drainage basins. The map illustrates a complex intersection of federal land management, where the Ross Lake National Recreation Area meets the Mt Baker Snoqualmie National Forest and the Pasayten Wilderness. This overlap highlights a preserved backcountry accessible primarily by trails and remote landmarks like the Bear Skull Shelter. The hydrological network is intricately mapped, showing the headwaters of Devils Creek and its North Fork, along with high-elevation water bodies such as the Jerry Lakes. Transitions in topography are noted at Dry Creek Pass and over summits like Devils Dome and Spratt Mountain, providing a detailed record of this alpine environment before the mid-2000s.
