About this map

South Fork Payette River carves through this portion of Boise County, serving as the primary corridor for movement and recreation. Along its banks, the Bonneville Hot Springs and Warm Springs Campground mark established points for visitors entering from Grandjean Rd. The landscape is dominated by steep drainages, including Warm Spring Creek and Eightmile Creek, which flow toward the river from the flanks of Eightmile Mountain.

Remote infrastructure is centered near the river's bend, where the Warm Springs Creek Airport and the Penrod Access Area facilitate access to the interior. Several high-elevation streams such as South Fork Cat Creek and Castro Creek define the northern reaches of the quadrangle, illustrating the complex hydrology of this part of the Idaho wilderness just after the first decade of the 21st century.
