The Carnuel 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.
71° on Nov. 16, 2025, the hottest reading for this week of the year since 1991. Next is 70° in 2021.
Carnuel’s center stands about 5,820 ft above sea level. Within three miles the land runs from 5,570 ft to 8,070 ft, a difference of 2,500 ft: mountain country. The highest named summit within 15 miles is North Sandia Peak, about 10,380 ft, 12 miles north.
Under the town center the state geologic map shows Mesoproterozoic granitic plutonic rocks, from the Mesoproterozoic, 1.2 to 1.6 billion years old.
The section below crosses 8 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.
Granitic. Age: Mesoproterozoic, 1.2 to 1.6 billion years old. About 9 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Limestone, sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, shale, siltstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 2 mi of the line.
Metavolcanic, metaclastic, gneiss. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 1 mi of the line.
Sandstone, carbonate, evaporite. Age: Permian, 273 to 290 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Carnuel reaches the Gulf of America by way of Tijeras Arroyo and the Rio Grande: about 1,560 river miles.
Lakes on the way: Paz Ramirez Lake, Amistad Reservoir, Elephant Butte Reservoir and Caballo Reservoir.
760 miles of the trip are on the Rio Grande.

Carnuel has a cold semi-arid climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Carnuel normally reaches 55° and falls to 33°. The record high is 69°, in 1999; the record low 15°, in 2018. The most rain on this date, 0.29 in, fell in 1993.
