Timbercreek Canyon’s center stands about 3,510 ft above sea level. Within three miles the land runs from 3,380 ft to 3,620 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Dockum Group, undivided (shale), from the Middle Triassic to Late Triassic, 208 to 247 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. 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: Pleistocene, less than 2.6 million years old. About 19 mi of the line.
Shale. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 3 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 1 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 1.0 mi of the line.
Clay, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.

A raindrop that lands in Timbercreek Canyon reaches the Gulf of America by way of the Prairie Dog Town Fork Red, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,330 river miles.
1,040 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Timbercreek Canyon; river miles along the main stem, rounded.
Timbercreek Canyon has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 25° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Timbercreek Canyon normally reaches 62° and falls to 34°. The record high is 85°, in 2025; the record low 5°, in 1916. The most rain on this date, 1.09 in, fell in 1924.
