Andrews’s center stands about 3,180 ft above sea level. Within three miles the land runs from 3,140 ft to 3,220 ft, a difference of 80 ft: gently rolling country.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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: Pleistocene, less than 2.6 million years old. About 16 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 1 mi of the line.
Chemical. Age: Pleistocene to Holocene, less than 2.6 million 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.
