Crouch’s center stands about 3,130 ft above sea level. Within three miles the land runs from 3,020 ft to 6,200 ft, a difference of 3,180 ft: mountain country. The highest named summit within 15 miles is Scott Mountain, about 8,130 ft, 10 miles east-northeast.
Under the town center the state geologic map shows Sedimentary rocks associated with flood basalts (mixed-clastic), from the Early Miocene to Late Miocene, 8 to 17 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 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite, granite. Age: Early Cretaceous to Late Cretaceous, 67 to 107 million years old. About 14 mi of the line.
Tonalite, granodiorite, quartz-diorite. Age: Late Cretaceous, 70 to 100 million years old. About 9 mi of the line.
Mixed-clastic. Age: Early Miocene to Late Miocene, 8 to 17 million years old. About 1 mi of the line.
Gravel, sand, silt. Age: Quaternary, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Crouch reaches the Pacific Ocean by way of the Middle Fork Payette, the Payette, the Snake and the Columbia: about 760 river miles.
Lakes on the way: Lake Umatilla, Brownlee Reservoir and Hells Canyon Reservoir.
240 miles of the trip are on the Snake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crouch; river miles along the main stem, rounded.
Crouch has a dry-summer warm-summer continental climate. Summer afternoons average 92° in July; winter nights fall to about 15° in January. About 22 inches of rain fall in a normal year.
On November 14 Crouch normally reaches 49° and falls to 22°. The record high is 69°, in 1999; the record low 11°, in 1993. The most rain on this date, 0.52 in, fell in 1941.
