−6° on Nov. 16, 1955, the coldest reading for this week of the year since 1909. Next is 2° in 1916.
Lake Shore’s center stands about 4,520 ft above sea level. Within three miles the land runs from 4,480 ft to 4,560 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Provo Peak, about 10,970 ft, 12 miles northeast.
Under the town center the state geologic map shows Lake Bonneville deposits (clay), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 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.
Clay. Age: Pleistocene, less than 2.6 million years old. About 14 mi of the line.
Dolostone, limestone. Age: Middle Cambrian, 497 to 521 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Limestone, dolostone. Age: Late Devonian to Early Mississippian, 347 to 374 million years old. About 0.3 mi of the line.

A raindrop that lands in Lake Shore reaches Great Salt Lake by way of Benjamin Slough and the Jordan: about 70 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Lake on the way: Utah Lake.
50 miles of the trip are on the Jordan.

Lake Shore has a dry-summer hot-summer continental climate. Summer afternoons average 93° in July; winter nights fall to about 22° in January. A normal year brings about 66 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Lake Shore normally reaches 52° and falls to 32°. The record high is 73°, in 1967; the record low 4°, in 1916. The most rain on this date, 1.18 in, fell in 1927.
Normals 1991–2020 and records since 1909 at Spanish Fork Power House, 7 miles east-southeast, 200 ft higher. NOAA, through RCC-ACIS.
