About this map

Badger Butte and Lookout Butte dominate this high-elevation landscape along the border of Marion, Wasco, and Jefferson counties. The map centers on a series of glacial lakes and high-altitude basins, including the namesake Boulder Lake and the nearby Trout Lake. This remote region is defined by its complex drainage systems, where headwaters such as the N Fork Boulder Creek and S Fork Boulder Creek converge.

Evidence of historical land management and access is found in the extensive network of forest roads like NW Trout Lake Road and BIA Road 33. In the southern portion of the quadrangle, the terrain transitions toward Shitike Creek and the open ground of Peters Pasture. The map highlights the volcanic character of the area through landmarks such as the Cinder Cone and Cedar Butte, offering a clear picture of the Cascades' geological and hydrological makeup in the early 21st century.
