About this map

Marion Lake serves as the centerpiece of this high-elevation landscape in the Cascades, where glacial basins and volcanic features define the terrain. The presence of Camp Marion on the lake’s eastern shore indicates the area's long-standing use for recreation and seasonal residency. The geography is characterized by an extensive network of alpine water bodies, from the prominent Lake of the Woods and Jefferson Lake to smaller, secluded basins like Patsy Lake and Midget Lake.

Volcanic activity has clearly shaped the skyline, evident in landmarks such as North Cinder Peak, South Cinder Peak, and the distinct formation of The Table. This 2011 survey also captures critical transit points through the mountains, most notably Minto Pass, which historically provided a route across the divide. The hydrology is equally complex, with Gatch Falls marking a sharp descent for the drainage flowing west through the densely forested drainage basins of Lizard Ridge and Rockpile Mountain.
