Sumner’s center stands about 1,040 ft above sea level. Within three miles the land runs from 940 ft to 1,190 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Chimney Rock, about 1,240 ft, 11 miles southeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 24 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 Sumner reaches the Gulf of America by way of the South Fork Buffalo, the Buffalo and the Mississippi: about 1,800 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sumner; river miles along the main stem, rounded.
