Lawn’s center stands about 1,920 ft above sea level. Within three miles the land runs from 1,870 ft to 1,990 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Flat Top Mountain, about 2,360 ft, 15 miles west.
Under the town center the state geologic map shows Clear Fork Group (claystone), from the Permian, 252 to 299 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Lawn reaches the Gulf of America by way of Red Bank Creek, Jim Ned Creek, Pecan Bayou and the Colorado: about 640 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, Brownwood Lake and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lawn; river miles along the main stem, rounded.
Lawn has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 34° in January. About 25 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Lawn normally reaches 68° and falls to 44°. The record high is 89°, in 2025; the record low 14°, in 1976. The most rain on this date, 1.54 in, fell in 1954.
