2024 Map of Twin Sisters

USGS Topo · Published 2024

About this map

Twin Sisters and the surrounding high country define this rugged section of the Idaho landscape, where the administrative boundaries of Adams, Washington, and Gem counties converge. The terrain is a complex network of steep drainages and ridges, protected by the Payette National Forest and Boise National Forest. The Little Weiser River carves through the northern reaches, accessible via the Little Weiser River Rd, while internal drainage is managed by numerous named gulches and creeks, including Grizzly Creek and Carson Gulch. High points like Buck Mtn and the Mill Creek Summit provide significant local elevation, overseeing a wilderness landscape primarily shaped by natural topography rather than permanent settlements. This modern survey demonstrates the persistence of traditional land use and water management in the region, centered on features like Chief Eagle Eye Creek and the Third Fork Ridge.
