3.32 inches of rain fell in two days, the most for this week of the year since records began in 1894. The next wettest, 2.19 inches, fell in 1903.
Lake City’s center stands about 4,810 ft above sea level. Within three miles the land runs from 4,450 ft to 7,460 ft, a difference of 3,010 ft: mountain country. The highest named summit within 15 miles is Bald Mountain, about 8,240 ft, 3 miles southwest.
Under the town center the state geologic map shows Tertiary pyroclastic and volcanic mudflow deposits, unit 9 (Cascade Range) (andesite), from the Late Oligocene to Pleistocene, 2 to 24 million years old.
The section below crosses 5 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.
Andesite. Age: Late Oligocene to Pleistocene, 2 to 24 million years old. About 11 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 10 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Paleocene to Pliocene, 2.6 to 66 million years old. About 0.8 mi of the line.
Andesite, basalt. Age: Late Oligocene to Pleistocene, 2 to 24 million years old. About 0.7 mi of the line.

A raindrop that lands in Lake City reaches Upper Lake by way of Wilkinson Creek: about 3 river miles. Upper 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 Lake City; river miles along the main stem, rounded.
Lake City has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 21° in December. A normal year brings about 22 inches of snow; with the rain, that comes to about 13 inches of water.
On November 14 Lake City normally reaches 52° and falls to 27°. The record high is 70°, in 1999; the record low 5°, in 2022. The most rain on this date, 2.70 in, fell in 1957.
Normals 1991–2020 and records since 1894 at Cedarville, 8 miles south-southeast, 120 ft lower. NOAA, through RCC-ACIS.
