75° on Nov. 11, 1973, the hottest reading for this week of the year since 1911. Next is 74° in 1934.
Eagar’s center stands about 7,090 ft above sea level. Within three miles the land runs from 6,920 ft to 8,000 ft, a difference of 1,080 ft: steep hill country. The highest named summit within 15 miles is Escudilla Mountain, about 10,920 ft, 14 miles southeast.
Under the town center the state geologic map shows Oligocene to Paleocene[?] sedimentary rocks (conglomerate, sandstone), from the Early Paleocene to Early Oligocene, 30 to 65 million 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 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, sandstone. Age: Early Paleocene to Early Oligocene, 30 to 65 million years old. About 10 mi of the line.
Basalt. Age: Early Pliocene to Holocene, less than 4 million years old. About 10 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 88 to 97 million years old. About 2 mi of the line.
Basalt, andesite, dacite. Age: Middle Eocene to Late Miocene, 11 to 38 million years old. About 0.9 mi of the line.
Conglomerate, sandstone. Age: Early Miocene to Pleistocene, 2 to 16 million years old. About 0.6 mi of the line.

A raindrop that lands in Eagar reaches the Gulf of California by way of the Little Colorado and the Colorado: about 1,070 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
340 miles of the trip are on the Little Colorado.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eagar; river miles along the main stem, rounded.
Eagar has a cold semi-arid climate. Summer afternoons average 85° in June; winter nights fall to about 16° in January. About 11 inches of rain fall in a normal year.
On November 14 Eagar normally reaches 60° and falls to 22°. The record high is 74°, in 2017; the record low 0°, in 1916. The most rain on this date, 0.91 in, fell in 1961.
