5° on Nov. 13, 2018, the coldest reading for this week of the year since 1977. Next is 7° in 2012.
Bibo’s center stands about 6,210 ft above sea level. Within three miles the land runs from 5,990 ft to 7,750 ft, a difference of 1,760 ft: steep hill country. The highest named summit within 15 miles is Mount Taylor, about 11,280 ft, 13 miles west-northwest.
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 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.
Shale, sandstone. Age: Late Cretaceous, 94 to 100 million years old. About 8 mi of the line.
Dacite, andesite, rhyolite. Age: Tertiary Neogene, 2.6 to 23 million years old. About 6 mi of the line.
Basalt, andesite. Age: Pliocene, 2.6 to 5.3 million years old. About 5 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million years old. About 3 mi of the line.
Sandstone, shale. Age: Late Jurassic, 145 to 164 million years old. About 2 mi of the line.
Shale, limestone. Age: Late Cretaceous, 90 to 100 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Bibo reaches the Gulf of America by way of Seboyetita Creek, the Rio Moquino, the Rio Paguate, the Rio San Jose, the Rio Puerco and the Rio Grande: about 1,610 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 Bibo; river miles along the main stem, rounded.
Bibo has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 18° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Bibo normally reaches 59° and falls to 25°. The record high is 76°, in 1999; the record low 12°, in 2018. The most rain on this date, 0.12 in, fell in 2001.
Normals 1991–2020 and records since 1977 at Cubero, 9 miles southwest. NOAA, through RCC-ACIS.
