About this map

Kachess Lake and its smaller counterpart, Little Kachess Lake, dominate this mountain corridor of the Cascades as they appeared in the late 1980s. Managed water levels are evident at the Kachess Dam and its associated Intake and Gaging Station, which regulate the flow into the Kachess River. The landscape is a mix of high-elevation peaks including Thorp Mountain and Amabilis Mountain, all contained within the Wenatchee National Forest.

Transportation and infrastructure are concentrated in the southern portion of the quadrangle, where I-90 follows the path of the Yakima River. This valley floor serves as a recreational and logistical hub, featuring Lake Easton State Park and the Easton State Airport. Geologic utility is noted at a Quarry near the base of Domerie Ridge, while several transmission lines cut through the timbered slopes to provide power across the mountain passes.
