64° on Nov. 11, 1980, the hottest reading for this week of the year since 1893. Next is 64° in 1999.
Breckenridge’s center stands about 9,740 ft above sea level. Within three miles the land runs from 9,360 ft to 11,580 ft, a difference of 2,220 ft: mountain country. The highest named summit within 15 miles is Mount Lincoln, about 14,230 ft, 10 miles south-southwest.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 6 mi of the line.
Biotite-gneiss, schist, migmatite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Granitic, dioritic. Age: Late Cretaceous to Middle Eocene, 40 to 72 million years old. About 4 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Limestone. Age: Cambrian to Carboniferous, 324 to 542 million years old. About 2 mi of the line.
Alkali-feldspar-granite, granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Breckenridge reaches the Gulf of California by way of the Blue River and the Colorado: about 1,400 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
380 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.

Breckenridge has a subarctic climate. Summer afternoons average 75° in July; winter nights fall to about 2° in January. A normal year brings about 116 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Breckenridge normally reaches 42° and falls to 12°. The record high is 60°, in 1999; the record low −26°, in 1916. The most rain on this date, 0.45 in, fell in 1983.
Normals 1991–2020 and records since 1893 at Dillon 1 E, 10 miles north, 660 ft lower. NOAA, through RCC-ACIS.
