Redvale’s center stands about 6,490 ft above sea level. Within three miles the land runs from 5,940 ft to 6,780 ft, a difference of 840 ft: hilly country. The highest named summit within 15 miles is Hamilton Mesa, about 8,960 ft, 13 miles south.
Under the town center the state geologic map shows Dakota Sandstone and Burro Canyon Fm (sandstone, shale, conglomerate), from the Early Cretaceous to Late Cretaceous, 66 to 145 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, shale, conglomerate. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 20 mi of the line.
Sandstone, mudstone, claystone. Age: Late Jurassic, 145 to 164 million years old. About 3 mi of the line.
Claystone, mudstone, sandstone. Age: Late Jurassic, 145 to 164 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Redvale reaches the Gulf of California by way of Naturita Creek, the San Miguel, the Dolores and the Colorado: about 1,180 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Redvale; river miles along the main stem, rounded.
