Liberty Hill’s center stands about 1,030 ft above sea level. Within three miles the land runs from 930 ft to 1,140 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Wildcat Mountain, about 1,400 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Glen Rose Limestone (limestone, marlstone), from the Early Cretaceous, 100 to 145 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 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, shale. Age: Early Cretaceous, 100 to 145 million years old. About 10 mi of the line.
Limestone, dolostone. Age: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 6 mi of the line.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 0.4 mi of the line.

A raindrop that lands in Liberty Hill reaches the Gulf of America by way of the South Fork San Gabriel, the San Gabriel, the Little River and the Brazos: about 440 river miles.
Lake on the way: Granger Lake.
320 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Liberty Hill; river miles along the main stem, rounded.
Liberty Hill has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 37 inches of rain fall in a normal year.
On November 14 Liberty Hill normally reaches 70° and falls to 47°. The record high is 86°, in 2006; the record low 26°, in 2018. The most rain on this date, 0.41 in, fell in 1998.
Normals 1991–2020 and records since 1980 at Georgetown Lake, 12 miles east, 160 ft lower. NOAA, through RCC-ACIS.
