1963 Map of Mt Logan

About this map

Mt Logan towers over a landscape defined by massive ice fields and high-altitude drainage systems along the boundary of Skagit Co and Chelan Co. This mid-century survey captures a period when North Cascades National Park and Mt Baker National Forest shared management of this glacial wilderness. The map reveals an intricate network of moving ice, from the Douglas Glacier and Fremont Glacier on the southern slopes of the peak to the Katsuk Glacier and Kimtah Glacier tucked beneath the peaks of Ragged Ridge. Evidence of human activity is sparse, limited to high-country navigation points like Rock Cabin and the Cascade Crest Trail. Dramatic natural processes are documented with labels such as the Rock Cabin Avalanche, showing the constant state of change in these high basins near North Fork Meadows.
