Ranchitos East’s center stands about 550 ft above sea level. Within three miles the land runs from 470 ft to 660 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Yegua Formation (claystone, sandstone), from the Eocene, 34 to 56 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 12 mi of the line.
Sandstone, claystone. Age: Eocene, 34 to 56 million years old. About 9 mi of the line.

A raindrop that lands in Ranchitos East reaches the Gulf of America by way of Chacon Creek and the Rio Grande: about 370 river miles.
Lake on the way: Paz Ramirez Lake.
270 miles of the trip are on the Rio Grande.
