2017 Map of Long Gulch

About this map

The South Fork Boise River cuts a deep path through this corner of the Boise National Forest, defining a landscape where steep canyons meet high plateaus. This area, dominated by the drainage systems of Blacks Creek and Corral Creek, reflects the specialized land management and recreation patterns of Elmore County. High points like Flatiron Mountain, Krall Mountain, and Grape Mountain provide vertical relief, while the Lower Bench and Smith Prairie suggest the presence of more level, usable terrain above the river valley. A dense network of forest access routes, including Rattlesnake Loop and several numbered spurs, spiderwebs across the ridges of Rattlesnake Ridge, showing the modern infrastructure required for forest service and backcountry access in the canyon country.
