The Midway 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.
70° on Nov. 16, 1999, the hottest reading for this week of the year since 1913. Next is 69° in 1967.
Midway’s center stands about 5,590 ft above sea level. Within three miles the land runs from 5,400 ft to 7,730 ft, a difference of 2,330 ft: mountain country. The highest named summit within 15 miles is Mount Timpanogos, about 11,560 ft, 12 miles southwest.
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 10 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: Quaternary, less than 2.6 million years old. About 9 mi of the line.
Sandstone, limestone. Age: Permian, 273 to 299 million years old. About 4 mi of the line.
Arenite. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 3 mi of the line.
Andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene, 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. 4 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Midway reaches Great Salt Lake by way of Snake Creek, the Provo and the Jordan: about 95 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Lakes on the way: Utah Lake and Deer Creek Reservoir.
50 miles of the trip are on the Jordan.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Midway; river miles along the main stem, rounded.
Midway has a dry-summer warm-summer continental climate. Summer afternoons average 88° in July; winter nights fall to about 14° in January. About 22 inches of rain fall in a normal year.
On November 14 Midway normally reaches 46° and falls to 23°. The record high is 69°, in 1967; the record low −4°, in 1916. The most rain on this date, 1.80 in, fell in 1955.
