About this map

Smith Prairie dominates the northern reaches of this Idaho landscape, where the high, flat ground supports the Smith Prairie Airport and the historic Smith Prairie Cem. This elevated plateau is deeply dissected by the winding course of the South Fork Boise River, which carves through the terrain past distinctive geological landmarks like Steamboat Rock and into the depths of Block Canyon. The elevation change is dramatic as the prairie gives way to the high peaks of the Danskin Mountains and Danskin Ridge to the south.

Contained largely within the Boise National Forest, the region is marked by a network of drainage systems including Rock Creek, Pierce Creek, and Granite Creek. Early transportation and access routes are preserved in the mapping of the Prairie-Pine Road and the Prairie Cutoff, alongside backcountry paths like the Granite Creek Trl. From the summit of Granite Mtn to the secluded Tommy Brú Spring, the map identifies the essential water sources and terrain features that have historically defined movement through this part of Elmore County.
