The Valmy 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.
78° on Nov. 16, 2021, the hottest reading for this week of the year since 1944. Next is 75° in 2019.
Valmy’s center stands about 4,520 ft above sea level. Within three miles the land runs from 4,430 ft to 4,820 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is North Peak, about 8,520 ft, 8 miles south.
Under the town center the state geologic map shows Older alluvium and alluvial fan deposits (coarse-detrital, fine-detrital), from the Pliocene to Pleistocene, less than 5.3 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 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 10 mi of the line.
Coarse-detrital, fine-detrital. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 8 mi of the line.
Age: Cambrian to Devonian, 359 to 497 million years old. About 5 mi of the line.
Sandstone, shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.

A raindrop that lands in Valmy reaches the Great Basin by way of Trout Creek, Herrin Slough and the Humboldt: about 230 river miles. The Great Basin 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 Valmy; river miles along the main stem, rounded.
Valmy has a cold semi-arid climate. Summer afternoons average 99° in July; winter nights fall to about 22° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 9 inches of water.
On November 14 Valmy normally reaches 58° and falls to 28°. The record high is 71°, in 2021; the record low 0°, in 1964. The most rain on this date, 0.78 in, fell in 1946.
