88° on Nov. 17, 2021, the hottest reading for this week of the year since 1932. Next is 87° in 1938.
McCamey’s center stands about 2,450 ft above sea level. Within three miles the land runs from 2,360 ft to 2,700 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is King Mountain, about 3,140 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Quaternary deposit, undivided (coarse-detrital, fine-detrital), from the Quaternary, less than 2.6 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 22×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 16 mi of the line.
Limestone, dolostone, marl. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Limestone, sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Claystone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.

A raindrop that lands in McCamey reaches the Gulf of America by way of the Pecos and the Rio Grande: about 800 river miles.
Lakes on the way: Paz Ramirez Lake and Amistad Reservoir.
270 miles of the trip are on the Rio Grande.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of McCamey; river miles along the main stem, rounded.
McCamey has a hot semi-arid climate. Summer afternoons average 96° in June; winter nights fall to about 33° in January. About 15 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 McCamey normally reaches 70° and falls to 43°. The record high is 85°, in 2011; the record low 14°, in 1976. The most rain on this date, 0.48 in, fell in 1968.
