Robert Lee’s center stands about 1,830 ft above sea level. Within three miles the land runs from 1,780 ft to 2,010 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Meadow Mountain, about 2,560 ft, 11 miles northwest.
Under the town center the state geologic map shows Terrace deposits (sand), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. 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, shale. Age: Permian, 252 to 299 million years old. About 10 mi of the line.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
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 Robert Lee reaches the Gulf of America by way of Mountain Creek and the Colorado: about 710 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls 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 Robert Lee; river miles along the main stem, rounded.
