2023 Map of Palm Lake

About this map

Sprague Lake dominates the northwest corner of this landscape in Adams County, where the rocky terrain of the Channeled Scablands meets modern recreational and transportation corridors. The map identifies the small, quiet locales of Ashby and Rockwell, which sit along the path of the Columbia Plateau State Park Trl. This trail follows an important historical rail alignment that once moved goods and people through the arid interior of Washington. Water defines the topography here, from the larger expanse of Sprague Lake and its prominent Harper Island to the smaller, secluded Palm Lake. The drainage network, including Cow Creek, McElroy Creek, and Lugenbeal Creek, illustrates how seasonal flows have carved into the basalt. Rural access is maintained via Danekas Rd and Sprague Lake Rd, connecting the scattered ranchlands and townships.
