The Cressey 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.
22° on Nov. 15, 1905, the coldest reading for this week of the year since 1899. Next is 24° in 1938.
Cressey’s center stands about 170 ft above sea level. Within three miles the land runs from 100 ft to 190 ft, a difference of 90 ft: gently rolling country.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Quaternary, less than 2.6 million years old. About 12 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 7 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Cressey has a cold semi-arid climate. Summer afternoons average 96° in July; winter nights fall to about 36° in December. About 12 inches of rain fall in a normal year.
On November 14 Cressey normally reaches 67° and falls to 41°. The record high is 81°, in 1933; the record low 25°, in 1938. The most rain on this date, 1.57 in, fell in 1953.
