The Snyder 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.
89° on Nov. 11, 2006, the hottest reading for this week of the year since 1911. Next is 88° in 1933.
Snyder’s center stands about 2,320 ft above sea level. Within three miles the land runs from 2,280 ft to 2,420 ft, a difference of 140 ft: gently rolling country.
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 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 15 mi of the line.
Shale. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 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.

A raindrop that lands in Snyder reaches the Gulf of America by way of the Colorado: about 820 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, E V Spence Reservoir 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 Snyder; river miles along the main stem, rounded.
Snyder has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 29° in January. About 22 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Snyder normally reaches 66° and falls to 39°. The record high is 88°, in 1933; the record low 15°, in 1940. The most rain on this date, 1.28 in, fell in 2001.
