−18° on Nov. 16, 1955, the coldest reading for this week of the year since 1919. Next is −2° in 1978.
Bloomington’s center stands about 5,970 ft above sea level. Within three miles the land runs from 5,920 ft to 6,790 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Paris Peak, about 9,510 ft, 8 miles west.
Under the town center the state geologic map shows Alluvial deposits (gravel, sand, silt), from the Quaternary, less than 2.6 million years old.
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 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.
Gravel, sand, silt. Age: Quaternary, less than 2.6 million years old. About 9 mi of the line.
Dolostone, limestone, sandstone. Age: Ordovician to Devonian, 359 to 487 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 4 mi of the line.
Mixed-clastic, volcanic. Age: Early Miocene to Pleistocene, 2 to 16 million years old. About 3 mi of the line.
Mudstone, sandstone, limestone. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Age: Neoproterozoic to Cambrian, 487 to 1,000 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 Bloomington reaches Great Salt Lake by way of Bloomington Creek and the Bear River: about 260 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bloomington; river miles along the main stem, rounded.
Bloomington has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 8° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Bloomington normally reaches 41° and falls to 21°. The record high is 60°, in 1967; the record low −2°, in 1978. The most rain on this date, 0.72 in, fell in 1958.
