About this map

Swasey Bottom defines the northern expanse of this Millard County landscape, a low-lying area that gives way to the drainage of Swasey Wash in the southeast. Water management is central to the human footprint here, as evidenced by the placement of Swasey Reservoir Number 2 and Swasey Reservoir Number 3 along the desert floor. These catchments, tied to the Swasey name that dominates the local geography, highlight the critical nature of water storage in Utah's arid interior.

A network of unpaved roads provides access through the valley, including the primary north-south artery of Swazey Spring Rd and the Laird Peak Rd branching toward the higher ground of the northeast. To the far north, Black Point serves as a prominent navigational marker where the terrain begins its ascent. The layout of these routes, including N Drum Mt Rd and Drum Mt Rd, illustrates a pattern of range management and mineral exploration characteristic of this region.
