80° on Nov. 14, 1999, the hottest reading for this week of the year since 1981. Next is 75° in 1990.
Lake Arrowhead’s center stands about 1,010 ft above sea level. Within three miles the land runs from 870 ft to 1,080 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 15 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.

A raindrop that lands in Lake Arrowhead reaches the Gulf of America by way of the Muddy Fork, Clear Creek, the Fishing, the Missouri and the Mississippi: about 1,530 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Arrowhead; river miles along the main stem, rounded.
Lake Arrowhead has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 16° in January. About 40 inches of rain fall in a normal year.
On November 14 Lake Arrowhead normally reaches 54° and falls to 32°. The record high is 80°, in 1999; the record low 11°, in 2014. The most rain on this date, 0.43 in, fell in 2024.
