About this map

Bull Run Reservoir lies at the southern edge of this high-elevation landscape, where the Bull Run Mountains descend into the Bull Run Basin. The terrain is defined by deep incisions like Echo Canyon, Edgemont Canyon, and Dunn Canyon, which drain the eastern heights of the Humboldt National Forest. High peaks including Blue Jacket Peak and Porter Peak dominate the eastern quadrant, while the northern expanse transitions into the broader Silver Creek Valley.

Evidence of ranching and remote aviation is seen at the Petan Ranch Airport near the intersection of Owyhee Rd. This area reflects a classic Great Basin drainage pattern, where seasonal waters from Silver Cr and Ranch Cr cut through narrow passages like Devils Gap. The map provides a detailed view of the rugged access routes, including the Porter and Edgemont tracks, which navigate the steep gradients of the gulches and canyons.
