11° on Nov. 14, 1976, the coldest reading for this week of the year since 1879. Next is 15° in 1880.
Morning Glory’s center stands about 3,630 ft above sea level. Within three miles the land runs from 3,620 ft to 3,900 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Backbone Hill, about 4,200 ft, 13 miles northeast.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Fine-detrital, sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 2 mi of the line.
Fine-detrital. Age: Pleistocene to Holocene, less than 2.6 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 Morning Glory reaches the Gulf of America by way of the Riverside Canal and the Rio Grande: about 1,230 river miles.
Lakes on the way: Paz Ramirez Lake and Amistad Reservoir.
610 miles of the trip are on the Rio Grande.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morning Glory; river miles along the main stem, rounded.
Morning Glory has a hot desert climate. Summer afternoons average 97° in June; winter nights fall to about 34° in December. About 9 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Morning Glory normally reaches 68° and falls to 42°. The record high is 83°, in 2025; the record low 11°, in 1976. The most rain on this date, 0.85 in, fell in 2004.
Normals 1991–2020 and records since 1879 from the El Paso Area threaded record (El Paso International Airport, 19 miles north-northwest, 310 ft higher). NOAA, through RCC-ACIS.
