Dimmitt’s center stands about 3,870 ft above sea level. Within three miles the land runs from 3,800 ft to 3,910 ft, a difference of 110 ft: gently rolling country.
The section below crosses 2 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 24 mi of the line.
Clay, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Dimmitt has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 22° in January. A normal year brings about 10 inches of snow; with the rain, that comes to about 21 inches of water.
