Flute Springs’s center stands about 730 ft above sea level. Within three miles the land runs from 620 ft to 1,380 ft, a difference of 760 ft: hilly country. The highest named summit within 15 miles is Doublehead Mountain, about 1,660 ft, 14 miles northeast.
Under the town center the state geologic map shows Atoka Formation (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. 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 9 mi of the line.
Chert, limestone. Age: Carboniferous, 324 to 359 million years old. About 6 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.

Limestone, shale. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 0.4 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 Flute Springs reaches the Gulf of America by way of Sallisaw Creek, the Arkansas and the Mississippi: about 980 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 Flute Springs; river miles along the main stem, rounded.
