2023 Map of Lake Chaplain

About this map

Lake Chaplain and the rugged basins of the Snoqualmie National Forest dominate this landscape northeast of the Puget Sound. The terrain is defined by the steep drainage systems of the Sultan River and Pilchuck River, where features like Horseshoe Bend and Sultan Ridge reveal the complex topography of the Cascades foothills. In the southern portion of the map, the valley floor transitions into a more developed corridor along the river, where the settlements of Sultan and Startup are established. A network of rural routes, including Monroe Camp Rd and Old Pipeline Rd, connects these riverside communities to the upland water resources. The inclusion of smaller bodies of water such as Echo Lake, Ida Lake, and Japanese Lake highlights the high-elevation glacial lakes characteristic of this Snohomish County region.
