−4° on Nov. 17, 1958, the coldest reading for this week of the year since 1935. Next is 2° in 1938.
Imlay’s center stands about 4,230 ft above sea level. Within three miles the land runs from 4,140 ft to 5,030 ft, a difference of 890 ft: hilly country. The highest named summit within 15 miles is Star Peak, about 9,800 ft, 9 miles south.
Under the town center the state geologic map shows Playa, lake bed, and flood plain deposits (coarse-detrital, fine-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 8 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.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Coarse-detrital, fine-detrital. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 4 mi of the line.
Limestone, dolostone, shale. Age: Early Triassic to Late Triassic, 227 to 251 million years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Andesite, rhyolite, clastic. Age: Early Triassic to Middle Triassic, 237 to 252 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. 2 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 Imlay reaches the Great Basin by way of the Humboldt: about 85 river miles. The Great Basin 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 Imlay; river miles along the main stem, rounded.
Imlay has a cold semi-arid climate. Summer afternoons average 95° in July; winter nights fall to about 18° in December. About 8 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Imlay normally reaches 55° and falls to 25°. The record high is 69°, in 2016; the record low 9°, in 1985. The most rain on this date, 0.31 in, fell in 1947.
