The Orangeville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
75° on Nov. 14, 1999, the hottest reading for this week of the year since 1899. Next is 69° in 1903.
Orangeville’s center stands about 5,800 ft above sea level. Within three miles the land runs from 5,650 ft to 6,480 ft, a difference of 830 ft: hilly country. The highest named summit within 15 miles is Trail Mountain, about 10,060 ft, 15 miles northwest.
Under the town center the state geologic map shows Alluvium and colluvium (unconsolidated), from the Quaternary, less than 2.6 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 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. Age: Late Cretaceous, 72 to 100 million years old. About 9 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Siltstone-mudstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 4 mi of the line.
Sandstone-mudstone. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone. Age: Early Cretaceous to Late Cretaceous, 94 to 125 million 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Orangeville reaches the Gulf of California by way of Cottonwood Creek, the San Rafael, the Green River and the Colorado: about 1,210 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.

Orangeville has a cold semi-arid climate. Summer afternoons average 91° in July; winter nights fall to about 10° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Orangeville normally reaches 54° and falls to 20°. The record high is 75°, in 1999; the record low 1°, in 1904. The most rain on this date, 0.60 in, fell in 1909.
