2021 Map of Dumont Dunes

About this map

Sperry sits at the northern edge of this arid landscape, positioned near the dramatic descent of the Amargosa River as it carves through Amargosa Canyon. The terrain is defined by its shifting sands and ancient geological formations, where the extensive Dumont Dunes and Valjean Dunes dominate the topography. These massive dune systems are framed by the Sperry Hills to the northwest and the Dumont Hills to the northeast, illustrating the complex wind-driven deposition patterns of the northern Mojave Desert. To the south, the landscape opens into the broad expanse of the Silurian Valley, flanked by the Valjean Hills. This survey provides a precise modern record of the drainage patterns and land partitions across the California desert, capturing the stark geographic relationship between the river corridor and the surrounding basins.
