Shady Grove’s center stands about 700 ft above sea level. Within three miles the land runs from 600 ft to 870 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Hi Early Mountain, about 1,020 ft, 12 miles southeast.
Under the town center the state geologic map shows Boggy Formation (shale, sandstone), 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 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 15 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Shady Grove reaches the Gulf of America by way of Shady Grove Creek, Elk Creek, Dirty Creek, the Arkansas and the Mississippi: about 1,030 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 Shady Grove; river miles along the main stem, rounded.
Shady Grove has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 28° in January. About 43 inches of rain fall in a normal year.
On November 14 Shady Grove normally reaches 62° and falls to 39°. The record high is 81°, in 2025; the record low 21°, in 2018. The most rain on this date, 0.78 in, fell in 2020.
Normals 1991–2020 and records since 1996 at Muskogee Davis Field, 12 miles north-northeast. NOAA, through RCC-ACIS.
