Wheatcroft’s center stands about 380 ft above sea level. Within three miles the land runs from 350 ft to 500 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Obie Mound, about 760 ft, 11 miles west.
Under the town center the state geologic map shows Sturgis Formation (siltstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit 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 Wheatcroft reaches the Gulf of America by way of the Caney Fork, Craborchard Creek, the Tradewater, the Ohio and the Mississippi: about 1,100 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wheatcroft; river miles along the main stem, rounded.
