1983 Map of Silurian Valley

USGS Topo · Published 1983

About this map

The Silurian Valley floor dominates this landscape, defined by the stark drainage patterns of Salt Creek and the expansive Dry Sand Lake. To the west, the steep alluvial fans of the Avawatz Mountains spill into the basin, while the southern edge is marked by the Soda Mountains near the ephemeral Silver Lake. A clear human imprint remains in the form of an Old Railroad Grade running along the eastern edge of the valley, a relic of early 20th-century desert transit. The map also records several Borrow Pits and Transmission Lines, indicating the region's utility as a corridor for infrastructure despite the prevalence of Dry Wash and Dry Sand Wash features that characterize this arid environment.
