Redstone’s center stands about 7,250 ft above sea level. Within three miles the land runs from 7,100 ft to 11,270 ft, a difference of 4,170 ft: mountain country. The highest named summit within 15 miles is Snowmass Mountain, about 13,990 ft, 10 miles east-southeast.
Under the town center the state geologic map shows Maroon Fm (arkose, siltstone, conglomerate), from the Carboniferous to Permian, 252 to 324 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mafic-hypabyssal, felsic-hypabyssal. Age: Eocene to Miocene, 5.3 to 56 million years old. About 7 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Arkose, siltstone, conglomerate. Age: Carboniferous to Permian, 252 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Arkose, conglomerate, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone, mudstone, claystone. Age: Late Triassic to Late Jurassic, 145 to 237 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. 5 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Redstone reaches the Gulf of California by way of East Creek, the Crystal, the Roaring Fork and the Colorado: about 1,290 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 Redstone; river miles along the main stem, rounded.
