2020 Map of Alpha

About this map

Lake Cascade and the North Fork Payette River anchor this 2020 landscape in Valley County, Idaho. The town of Cascade sits along the northern edge, supported by the Cascade Airport and the Payette River Scenic Byway. The topography transitions from the open waters and the agricultural stretches of Long Valley into the high elevations of the Boise National Forest. To the west, the terrain rises sharply toward West Mountain, where peaks like Collier Peak and Tripod Peak overlook numerous high-country water bodies, including Skein Lake, Raft Lake, and the Willow Cr Reservoir. Small historic clusters such as Belvidere, Cabarton, and Alpha are located along the eastern valley floor, marking the corridor where rail and road routes follow the river's path through the mountain meadows.
