Mound’s center stands about 690 ft above sea level. Within three miles the land runs from 660 ft to 920 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Shell Mountains, about 1,210 ft, 12 miles west.
Under the town center the state geologic map shows Terrace deposits (sand), from the Pleistocene to Holocene, less than 2.6 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 37×. 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 8 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Claystone, limestone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Marlstone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 2 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 Mound reaches the Gulf of America by way of the Leon, the Little River and the Brazos: about 490 river miles.
Lake on the way: Belton 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 Mound; river miles along the main stem, rounded.
Mound has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 35 inches of rain fall in a normal year.
On November 14 Mound normally reaches 70° and falls to 46°. The record high is 89°, in 1989; the record low 24°, in 2018. The most rain on this date, 0.32 in, fell in 2015.
Normals 1991–2020 and records since 1983 at Killeen, 20 miles south, 120 ft higher. NOAA, through RCC-ACIS.
