Happy Valley’s center stands about 3,220 ft above sea level. Within three miles the land runs from 3,120 ft to 3,660 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Old Ranch Knoll, about 4,410 ft, 14 miles west.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, carbonate, siltstone. Age: Permian, 260 to 273 million years old. About 9 mi of the line.
Salt. Age: Permian, 252 to 260 million years old. About 4 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million years old. About 4 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Evaporite, mixed-clastic, dolostone. Age: Permian, 260 to 273 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.8 million years old. About 2 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 Happy Valley reaches the Gulf of America by way of the Pecos and the Rio Grande: about 1,100 river miles.
Lakes on the way: Paz Ramirez Lake, Amistad Reservoir and Red Bluff Reservoir.
410 miles of the trip are on the Pecos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Happy Valley; river miles along the main stem, rounded.
Happy Valley has a cold desert climate. Summer afternoons average 96° in June; winter nights fall to about 29° in January. About 12 inches of rain fall in a normal year.
On November 14 Happy Valley normally reaches 67° and falls to 37°. The record high is 86°, in 2025; the record low 10°, in 1976. The most rain on this date, 0.70 in, fell in 2004.
Normals 1991–2020 and records since 1930 at Cavern City Airport, 7 miles south-southeast. NOAA, through RCC-ACIS.
