76° on Nov. 15, 1999, the hottest reading for this week of the year since 1983. Next is 75° in 1989.
Ribera’s center stands about 6,020 ft above sea level. Within three miles the land runs from 5,970 ft to 7,030 ft, a difference of 1,060 ft: steep hill country. The highest named summit within 15 miles is Barillas Peak, about 9,360 ft, 14 miles north.
Under the town center the state geologic map shows Alluvium (unconsolidated), from the Pleistocene to Holocene, less than 0.1 million years old.
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 9×. 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 6 mi of the line.
Shale, limestone, mixed-clastic. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sandstone. Age: Permian, 273 to 290 million years old. About 4 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million 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.
Limestone, dolostone. Age: Permian, 260 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Ribera reaches the Gulf of America by way of the Pecos and the Rio Grande: about 1,480 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ribera; river miles along the main stem, rounded.
Ribera has a cold semi-arid climate. Summer afternoons average 85° in June; winter nights fall to about 11° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 17 inches of water.
On November 14 Ribera normally reaches 59° and falls to 20°. The record high is 75°, in 1999; the record low 10°, in 2000. The most rain on this date, 0.20 in, fell in 1993.
Normals 1991–2020 and records since 1983 at Las Vegas Waste Water Plant, 19 miles northeast, 330 ft higher. NOAA, through RCC-ACIS.
