2024 Map of Garden Valley

South of the river valley, the terrain rises into the Boise National Forest, marked by prominent high points such as Mica Dome and Mineral Mountain. The inclusion of Grimes Pass and various gulches like Schoolhouse Gulch suggests the historical movement through these mountains toward earlier mining districts. The road network, including the Banks Lowman Hwy, follows the natural contours of the river banks, illustrating the enduring relationship between the region's topography and its transportation corridors.
