The Hatch 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.
77° on Nov. 16, 2016, the hottest reading for this week of the year since 1904. Next is 72° in 1967.
Hatch’s center stands about 6,920 ft above sea level. Within three miles the land runs from 6,860 ft to 7,710 ft, a difference of 850 ft: hilly country. The highest named summit within 15 miles is Blue Spring Mountain, about 9,870 ft, 15 miles west.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 8 mi of the line.
Limestone, mudstone. Age: Late Paleocene to Early Oligocene, 28 to 59 million years old. About 8 mi of the line.
Sandstone-mudstone, sandstone. Age: Late Cretaceous, 72 to 94 million years old. About 2 mi of the line.
Felsic-volcanic, andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 2 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Conglomerate-sandstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Hatch reaches Sevier Lake by way of the Sevier: about 360 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hatch; river miles along the main stem, rounded.
Hatch has a cold semi-arid climate. Summer afternoons average 86° in July; winter nights fall to about 7° in December. A normal year brings about 25 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Hatch normally reaches 51° and falls to 16°. The record high is 72°, in 1967; the record low −4°, in 1938. The most rain on this date, 0.36 in, fell in 1988.
