About this map

Grimes Pass serves as a central landmark within the Boise National Forest in this 2020 record of Boise County’s high country. The landscape is defined by the South Fork Payette River and an intricate network of drainage systems, including Danskin Creek and Grimes Cr. The map details a rugged topography marked by numerous gulches, such as Ader Gulch, Miller Gulch, and Wet Gulch, which suggest a history of resource extraction and local land use.

Evidence of early infrastructure remains visible through labels like Schoolhouse Cr, hinting at former settlement sites now predominantly managed for forest use. Significant elevations like Scott Mountain, Gallagher Peak, and Jackson Peak tower over the river valleys, while the Banks-Lowman Hwy provides modern access through the terrain. For genealogists and local historians, the specific naming of features like Charlotte Gulch and Poorman Cr Land Rd provides geographic anchors for family names and historical land claims in this part of Idaho.
