4.26 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 4.06 inches, fell in 1902.
Stonewall’s center stands about 1,460 ft above sea level. Within three miles the land runs from 1,420 ft to 1,690 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Big Hill, about 2,010 ft, 12 miles southwest.
Under the town center the state geologic map shows Hensell Sand (limestone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Early Cretaceous, 100 to 145 million years old. About 11 mi of the line.
Limestone. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 2 mi of the line.
Limestone. Age: Middle Cambrian, 497 to 521 million years old. About 2 mi of the line.
Dolostone. Age: Cambrian, 487 to 497 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Stonewall reaches the Gulf of America by way of the Pedernales and the Colorado: about 420 river miles.
Lake on the way: Lake Marble Falls.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stonewall; river miles along the main stem, rounded.
Stonewall has a humid subtropical climate. Summer afternoons average 94° in August; winter nights fall to about 34° in January. About 31 inches of rain fall in a normal year.
On November 14 Stonewall normally reaches 68° and falls to 44°. The record high is 86°, in 2007; the record low 23°, in 1940. The most rain on this date, 2.16 in, fell in 2001.
Normals 1991–2020 and records since 1896 at Fredericksburg, 15 miles west, 220 ft higher. NOAA, through RCC-ACIS.
