Trout Valley’s center stands about 5,940 ft above sea level. Within three miles the land runs from 5,850 ft to 7,190 ft, a difference of 1,340 ft: steep hill country. The highest named summit within 15 miles is Black Peak, about 9,020 ft, 9 miles south.
Under the town center the state geologic map shows Lower-upper middle Tertiary basaltic andesites and andesites of the Mogollon Group (andesite, basaltic-andesite, basalt), from the Early Oligocene to Late Oligocene, 26 to 29 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 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basaltic-andesite, andesite. Age: Late Oligocene to Early Miocene, 22 to 26 million years old. About 8 mi of the line.
Andesite, basaltic-andesite, basalt. Age: Early Oligocene to Late Oligocene, 26 to 29 million years old. About 7 mi of the line.
Conglomerate-sandstone, volcanic. Age: Late Oligocene to Pleistocene, 0.1 to 28 million years old. About 6 mi of the line.
Felsic-volcanic. Age: Late Eocene to Early Oligocene, 31 to 36 million years old. About 3 mi of the line.
Andesite, dacite. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 0.8 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 Trout Valley reaches the Gulf of California by way of Sapillo Creek, the Gila and the Colorado: about 730 river miles.
590 miles of the trip are on the Gila.
Often dry. About 40% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Trout Valley; river miles along the main stem, rounded.
Trout Valley has a oceanic climate. Summer afternoons average 90° in June; winter nights fall to about 17° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Trout Valley normally reaches 65° and falls to 24°. The record high is 81°, in 1967; the record low 12°, in 2024. The most rain on this date, 0.38 in, fell in 1968.
Normals 1991–2020 and records since 1957 at Gila Hot Springs, 11 miles north, 300 ft lower. NOAA, through RCC-ACIS.
