Lake Chaplain dominates the high ground of this Snohomish County landscape, serving as a significant reservoir near the edge of the Snoqualmie National Forest. The map illustrates a complex network of water and terrain, where the Sultan River carves through the eastern portion of the quadrangle, flanked by the prominent elevations of Sultan Ridge and Haywire Ridge. This 2017 survey reflects a region defined by its managed timberlands and water resources, with the Sultan River's course featuring a sharp meander at Horseshoe Bend.
