The Aspermont plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
91° on Nov. 15, 2025, the hottest reading for this week of the year since 1911. Next is 88° in 2021.
Aspermont’s center stands about 1,780 ft above sea level. Within three miles the land runs from 1,710 ft to 1,880 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Double Mountains, about 2,550 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Blaine Formation (shale), from the Permian, 252 to 299 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Permian, 252 to 299 million years old. About 15 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Sandstone-mudstone. Age: Permian, 252 to 299 million years old. About 0.9 mi of the line.

A raindrop that lands in Aspermont reaches the Gulf of America by way of Rock Creek, the Salt Fork Brazos and the Brazos: about 940 river miles.
Lakes on the way: Possum Kingdom Lake and Lake Granbury.
550 miles of the trip are on the Brazos.

Aspermont has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 29° in January. About 24 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Aspermont normally reaches 66° and falls to 39°. The record high is 85°, in 2025; the record low 14°, in 1976. The most rain on this date, 2.03 in, fell in 1954.
