1988 Map of Grimes Pass

About this map

The rugged drainage of the South Fork Payette River and its numerous tributaries dominate this 1980s landscape in the Boise National Forest. The map centers on the high-elevation crossing of Grimes Pass, a location of significant local lore as noted by the Grimes Monument. This region reflects a long history of resource extraction, with multiple mining operations scattered across the steep gulches, including the Golden Age Mine, the Missouri Mine, and the Comeback Mine. The terrain is deeply incised by a complex network of waterways like Anderson Creek and Grimes Creek, while the presence of Basque Spring alludes to the historic sheep-herding traditions of the Idaho backcountry. Researchers will find a land defined by its mining claims and remote mountain peaks, such as the 7,351-foot Jackson Peak, served by a winding system of forest roads and trails.
