2021 Map of Gregerson Basin

About this map

Gregerson Basin sits at the heart of this high-desert landscape, tucked between the rising slopes of the Delamar Mountains to the east and the open expanse of Delamar Valley to the northwest. This 2021 survey reveals a territory where survival depends on dispersed water sources, marked by several named springs that have likely served as vital landmarks for generations. Jumbo Spring, Ben Hur Spring, Holly Spring, and Stewart Spring are scattered across the mountainous terrain, while Pony Reservoir sits in the flatter southwestern reaches. The drainage pattern is dominated by Jumbo Wash, which cuts across the northern quadrangle. This map documents the intersection of modern cartographic precision and the enduring, arid geography of Lincoln County.
