Oak Grove’s center stands about 780 ft above sea level. Within three miles the land runs from 720 ft to 910 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Reservoir Hill, about 1,010 ft, 11 miles west-northwest.
Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 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 46×. 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 7 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 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. 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 Oak Grove reaches the Gulf of America by way of the Cimarron, the Arkansas and the Mississippi: about 1,100 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oak Grove; river miles along the main stem, rounded.
