Eupora’s center stands about 390 ft above sea level. Within three miles the land runs from 360 ft to 520 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Sand Mountain, about 650 ft, 5 miles northwest.
Under the town center the state geologic map shows Wilcox formation (sand, clay), from the Eocene, 34 to 56 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Eocene, 34 to 56 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 Eupora reaches the Gulf of America by way of the Big Black and the Mississippi: about 680 river miles.
420 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eupora; river miles along the main stem, rounded.
