3.20 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 2.69 inches, fell in 2003.
Benjamin Perez’s center stands about 250 ft above sea level. Within three miles the land runs from 150 ft to 330 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Uvalde Gravel, from the Late Pliocene to Pleistocene, less than 3.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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. Age: Oligocene, 23 to 34 million years old. About 7 mi of the line.
Gravel. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 1 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.
Clay. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 0.5 mi of the line.

A raindrop that lands in Benjamin Perez reaches the Gulf of America by way of the Rio Grande: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Benjamin Perez; river miles along the main stem, rounded.
Benjamin Perez has a hot semi-arid climate. Summer afternoons average 99° in July; winter nights fall to about 45° in January. About 22 inches of rain fall in a normal year.
On November 14 Benjamin Perez normally reaches 79° and falls to 55°. The record high is 94°, in 1985; the record low 27°, in 2018. The most rain on this date, 0.56 in, fell in 1998.
