About this map

Arrowrock Dam and its accompanying Arrowrock Reservoir dominate the northern terrain, where the Boise River is managed for water storage and irrigation. This landscape is defined by its deep drainages and significant elevation changes, ranging from the canyon floor to high points such as Cervidae Peak and Kepros Mtn. The downstream impact of this water management system is visible at Lucky Peak Lake in the western portion of the map, illustrating the complex engineering of the Boise River basin.

A network of mountain roads and gulches, including Atlanta Road and Arrow Rock Rd, provides access through the Boise National Forest. These routes trace historical paths along the river and through named ravines like Long Gulch and Browns Gulch. The intersection of Boise, Ada, and Elmore counties occurs here, marking a rugged frontier where water resources and forestry have long been the primary human influences on the land.
