Mirando City’s center stands about 760 ft above sea level. Within three miles the land runs from 640 ft to 890 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Catahoula Formation (mudstone, sand), from the Oligocene, 23 to 34 million years old.
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 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 11 mi of the line.
Clay. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 11 mi of the line.
Clay. Age: Oligocene, 23 to 34 million years old. About 1 mi of the line.
Mudstone, sand. Age: Oligocene, 23 to 34 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.
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 Mirando City reaches the Gulf of America by way of Reiser Creek, Retama Creek, San Juanito Creek, Blancas Creek, Dolores Creek and the Rio Grande: about 380 river miles.
Lake on the way: Paz Ramirez Lake.
270 miles of the trip are on the Rio Grande.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mirando City; river miles along the main stem, rounded.
