63° on Nov. 11, 2016, the hottest reading for this week of the year since 1960. Next is 62° in 1969.
Rocky Point’s center stands about 4,220 ft above sea level. Within three miles the land runs from 4,140 ft to 5,770 ft, a difference of 1,630 ft: steep hill country. The highest named summit within 15 miles is Mount McLoughlin, about 9,400 ft, 10 miles west.
Under the town center the state geologic map shows Alluvial deposits (sand, gravel, silt), from the Holocene, less than 12,000 years old.
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 6×. 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, basalt. Age: Late Miocene to Early Pliocene, 4 to 9 million years old. About 9 mi of the line.
Basaltic-andesite, basalt. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Basaltic-andesite, basalt, andesite. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.
Basaltic-andesite, basalt. Age: Early Pliocene to Pleistocene, 1.2 to 3.9 million years old. About 2 mi of the line.
Gravel, sand, boulders. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Rocky Point reaches the Pacific Ocean by way of Varney Creek, the Link and the Klamath: about 290 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rocky Point; river miles along the main stem, rounded.
Rocky Point has a dry-summer warm-summer continental climate. Summer afternoons average 79° in July; winter nights fall to about 23° in January. A normal year brings about 118 inches of snow; with the rain, that comes to about 31 inches of water.
On November 14 Rocky Point normally reaches 42° and falls to 28°. The record high is 60°, in 1995; the record low 6°, in 1978. The most rain on this date, 2.12 in, fell in 2006.
Normals 1991–2020 and records since 1960 at Howard Prairie Dam, 20 miles southwest, 350 ft higher. NOAA, through RCC-ACIS.
