78° on Nov. 15, 1999, the hottest reading for this week of the year since 1975. Next is 78° in 2025.
La Bajada’s center stands about 5,470 ft above sea level. Within three miles the land runs from 5,380 ft to 6,230 ft, a difference of 850 ft: hilly country. The highest named summit within 15 miles is Cerro Picacho, about 8,050 ft, 15 miles north-northwest.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt, andesite. Age: Pliocene, 2.6 to 5.3 million years old. About 10 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Conglomerate-sandstone, coarse-detrital, fine-detrital. Age: Late Oligocene to Late Miocene, 5.3 to 28 million years old. About 3 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million years old. About 2 mi of the line.
Clastic, unconsolidated. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 0.9 mi of the line.
Conglomerate, sandstone, shale. Age: Tertiary Paleogene, 23 to 66 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. 1 smaller unit along the line are not listed.

A raindrop that lands in La Bajada reaches the Gulf of America by way of the Santa Fe and the Rio Grande: about 1,600 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Bajada; river miles along the main stem, rounded.
La Bajada has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 20° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 La Bajada normally reaches 61° and falls to 29°. The record high is 75°, in 2017; the record low 17°, in 2018. The most rain on this date, 0.34 in, fell in 1993.
Normals 1991–2020 and records since 1975 at Cochiti Dam, 8 miles northwest. NOAA, through RCC-ACIS.
