1991 Map of Chalk Knolls

USGS Topo · Published 1991

About this map

The Chalk Knolls rise sharply from the floor of the Tule Valley, a desert depression in western Millard County. This 1991 provisional map documents a landscape defined by its scarce water sources and dramatic topographic shifts between the basin floor and the eastern edge of the Confusion Range. The presence of Willow Spring, Tule Spring, and South Tule Spring highlights the critical points of hydration in an otherwise arid environment, connected primarily by the Tule Spring Road. To the southwest, the terrain transitions into Little Valley and an area labeled Cattlemens, suggesting the historical use of these basins for seasonal grazing. The map provides a meticulous record of benchmark elevations and section lines across these desert flats, useful for understanding the grazing and water-rights geography of this part of the Great Basin.
