63° on Nov. 12, 1999, the hottest reading for this week of the year since 1905. Next is 62° in 1934.
McCall’s center stands about 5,020 ft above sea level. Within three miles the land runs from 4,920 ft to 5,480 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Nick Peak, about 8,950 ft, 11 miles east.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt, basaltic-andesite. Age: Early Miocene to Late Miocene, 6 to 18 million years old. About 8 mi of the line.
Granodiorite, granite. Age: Early Cretaceous to Late Cretaceous, 67 to 107 million years old. About 7 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Schist, gneiss, amphibolite. Age: Permian to Cretaceous, 66 to 299 million years old. About 1 mi of the line.
Tonalite, granodiorite, quartz-diorite. Age: Late Cretaceous, 70 to 100 million years old. About 0.5 mi of the line.
Age: Mesoproterozoic to Paleozoic, 252 to 1,600 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in McCall reaches the Pacific Ocean by way of Payette Lake, the North Fork Payette, the Payette, the Snake and the Columbia: about 830 river miles.
Lakes on the way: Lake Cascade, Lake Umatilla, Brownlee Reservoir and Payette Lake.
240 miles of the trip are on the Snake.

McCall has a dry-summer warm-summer continental climate. Summer afternoons average 81° in July; winter nights fall to about 14° in January. About 23 inches of rain fall in a normal year.
On November 14 McCall normally reaches 41° and falls to 22°. The record high is 59°, in 1999; the record low 1°, in 1916. The most rain on this date, 0.86 in, fell in 1973.
