Deer’s center stands about 2,330 ft above sea level. Within three miles the land runs from 1,240 ft to 2,330 ft, a difference of 1,090 ft: steep hill country.
Under the town center the state geologic map shows Atoka Formation, undivided (sandstone, black-shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sandstone, black-shale. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Sandstone, shale, limestone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Deer reaches the Gulf of America by way of the East Fork Little Buffalo, the Little Buffalo, the Buffalo, the White River and the Mississippi: about 1,130 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Deer; river miles along the main stem, rounded.
