11° on Nov. 14, 1976, the coldest reading for this week of the year since 1879. Next is 15° in 1880.
Horizon City’s center stands about 4,030 ft above sea level. Within three miles the land runs from 3,770 ft to 4,040 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Backbone Hill, about 4,200 ft, 9 miles east.
Under the town center the state geologic map shows Sand sheet deposits, from the Holocene, less than 12,000 years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. 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 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Fine-detrital, sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Horizon City reaches the Gulf of America by way of the Riverside Canal and the Rio Grande: about 1,240 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 Horizon City; river miles along the main stem, rounded.
Horizon City 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 Horizon City 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.
