About this map

Grimes Pass serves as a central landmark in this Boise County landscape, where the South Fork Payette River and Grimes Creek drainage systems define the rugged topography. The area is marked by a clear history of resource extraction, evidenced by several mining sites concentrated in the southern half of the map. These include the Golden Age Mine, the Comeback Mine, and the Missouri Mine, which are situated among numerous named gulches like Mohawk Gulch and Ader Gulch.

Remote access is provided via the Banks Lowman Rd and White Cap Rd, which wind through the mountainous terrain past Gallagher Peak and Jackson Peak. Recreation is noted at the Pine Creek Campground and Forks of Big Pine Creek Campground in the northeast. The presence of features like Basque Spring and Gallagher Pasture suggests a legacy of seasonal land use and livestock grazing typical of the Idaho backcountry during this era.
