78° on Nov. 16, 2024, the hottest reading for this week of the year since 1978. Next is 77° in 2025.
Ojo Amarillo’s center stands about 5,400 ft above sea level. Within three miles the land runs from 5,120 ft to 5,650 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Pinon Mesa, about 6,180 ft, 10 miles north-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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. 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 10 mi of the line.
Sandstone, shale, conglomerate. Age: Paleocene, 56 to 66 million years old. About 5 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Mudstone, shale. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Shale. Age: Late Cretaceous, 72 to 100 million years old. About 2 mi of the line.
Conglomerate-sandstone, shale. Age: Paleocene, 56 to 66 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Ojo Amarillo reaches the Gulf of California by way of the San Juan and the Colorado: about 1,100 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ojo Amarillo; river miles along the main stem, rounded.
Ojo Amarillo 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 Ojo Amarillo 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.
