The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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. Age: Holocene, less than 12,000 years old. About 12 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 5 mi of the line.

A raindrop that lands in Seminole reaches the Gulf of America by way of Beals Creek and the Colorado: about 970 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, E V Spence Reservoir and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Seminole; river miles along the main stem, rounded.
