10° on Nov. 17, 2000, the coldest reading for this week of the year since 1996. Next is 11° in 2014.
Lazear’s center stands about 5,440 ft above sea level. Within three miles the land runs from 5,150 ft to 6,070 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Mount Lamborn, about 11,320 ft, 14 miles east.
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 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 9 mi of the line.
Sandstone, shale, conglomerate. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Sandstone, mudstone, claystone. Age: Late Jurassic, 145 to 164 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 2 mi of the line.
Unconsolidated. Age: Quaternary, 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.

A raindrop that lands in Lazear reaches the Gulf of California by way of the North Fork Gunnison, the Gunnison and the Colorado: about 1,240 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
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 Lazear; river miles along the main stem, rounded.
Lazear has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 16° in January. About 8 inches of rain fall in a normal year.
On November 14 Lazear normally reaches 52° and falls to 26°. The record high is 67°, in 2025; the record low 12°, in 2000. The most rain on this date, 0.20 in, fell in 2009.
Normals 1991–2020 and records since 1996 at Montrose Regional Airport, 20 miles south-southwest, 270 ft higher. NOAA, through RCC-ACIS.
