5.73 inches of rain fell in two days, the most for this week of the year since records began in 1951. The next wettest, 5.47 inches, fell in 2021.
Government Camp’s center stands about 3,910 ft above sea level. Within three miles the land runs from 3,070 ft to 5,970 ft, a difference of 2,900 ft: mountain country. The highest named summit within 15 miles is Mount Hood, about 11,150 ft, 6 miles north-northeast.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basaltic-andesite, andesite. Age: Quaternary, less than 2.6 million years old. About 9 mi of the line.
Basaltic-andesite, basalt. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Basaltic-andesite, basalt. Age: Early Pliocene to Pleistocene, 1.2 to 3.9 million years old. About 4 mi of the line.
Basaltic-andesite, andesite. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 3 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Age: Holocene, less than 12,000 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Government Camp reaches the Pacific Ocean by way of Camp Creek, the Zigzag, the Sandy and the Columbia: about 170 river miles.
120 miles of the trip are on the Columbia.

Government Camp has a dry-summer warm-summer continental climate. Summer afternoons average 70° in August; winter nights fall to about 26° in January. A normal year brings about 232 inches of snow; with the rain, that comes to about 90 inches of water.
On November 14 Government Camp normally reaches 42° and falls to 31°. The record high is 63°, in 1999; the record low 1°, in 1955. The most rain on this date, 1.80 in, fell in 2001.
