78° on Nov. 16, 2024, the hottest reading for this week of the year since 1978. Next is 77° in 2025.
Nenahnezad’s center stands about 5,160 ft above sea level. Within three miles the land runs from 5,060 ft to 5,430 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Pinon Mesa, about 6,180 ft, 9 miles northeast.
Under the town center the state geologic map shows Kirtland and Fruitland Formations (sandstone, shale), from the Late Cretaceous, 72 to 84 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 13×. 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, shale. Age: Late Cretaceous, 72 to 84 million years old. About 19 mi of the line.
Mudstone, shale, sandstone. Age: Late Cretaceous, 72 to 87 million years old. About 2 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 84 million years old. About 1 mi of the line.
Mudstone, shale. Age: Late Cretaceous, 72 to 84 million years old. About 0.6 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million years old. About 0.5 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 84 million years old. About 0.3 mi of the line.

A raindrop that lands in Nenahnezad reaches the Gulf of California by way of the San Juan and the Colorado: about 1,090 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

Nenahnezad has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 20° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Nenahnezad normally reaches 54° and falls to 29°. The record high is 77°, in 2025; the record low 17°, in 2010. The most rain on this date, 0.15 in, fell in 2011.
