The La Cueva 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.
−4° on Nov. 13, 2018, the coldest reading for this week of the year since 1916. Next is −3° in 2014.
La Cueva’s center stands about 7,340 ft above sea level. Within three miles the land runs from 6,970 ft to 8,390 ft, a difference of 1,420 ft: steep hill country. The highest named summit within 15 miles is Lake Peak, about 12,310 ft, 14 miles north.
Under the town center the state geologic map shows Permian and Pennsylvanian rocks, undivided (sandstone, limestone, dolostone), from the Carboniferous to Permian, 252 to 324 million years old.
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 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.
Sandstone, limestone, dolostone. Age: Carboniferous to Permian, 252 to 324 million years old. About 13 mi of the line.
Granitic, gneiss. Age: Paleoproterozoic, 1.6 to 1.7 billion years old. About 4 mi of the line.
Plutonic. Age: Paleoproterozoic to Mesoproterozoic, 1 to 2.5 billion years old. About 3 mi of the line.
Sandstone. Age: Permian, 273 to 290 million years old. About 2 mi of the line.
Pelitic-schist, muscovite-schist, quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Sandstone, carbonate, evaporite. Age: Permian, 273 to 290 million years old. About 0.5 mi of the line.

A raindrop that lands in La Cueva reaches the Gulf of America by way of Glorieta Creek, the Pecos and the Rio Grande: about 1,520 river miles.
Lakes on the way: Paz Ramirez Lake, Amistad Reservoir, Red Bluff Reservoir and Lake McMillan.
410 miles of the trip are on the Pecos.

La Cueva has a oceanic climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 La Cueva normally reaches 55° and falls to 26°. The record high is 74°, in 1949; the record low 1°, in 1940. The most rain on this date, 0.80 in, fell in 1997.
