2018 Map of Bighorn Basin

About this map

Mojave National Preserve encompasses this arid landscape, dominated by the massive rise of the Granite Mountains and the high elevations of Granite Peak and Silver Peak. The topography is defined by significant drainage systems such as Cottonwood Wash and Budweiser Wash, which carve through the high desert toward the central Bighorn Basin. Water remains the critical lifeline in this environment, marked by isolated points like Coyote Springs, Twin Springs, and Budweiser Spring. These features suggest a landscape where travel and survival were historically dictated by the location of these rare perennial sources. To the south, the Granite Peak Plateau gives way to Granite Cove and the unique formation known as White Fang, illustrating the geological complexity of the eastern Mojave Desert. The presence of several distinct springs and washes within the Willow Spring Basin further emphasizes the intricate hydrology found in this part of San Bernardino County.
