−5° on Nov. 17, 1903, the coldest reading for this week of the year since 1899. Next is 2° in 1916.
Boyds’s center stands about 1,350 ft above sea level. Within three miles the land runs from 1,280 ft to 3,400 ft, a difference of 2,120 ft: mountain country. The highest named summit within 15 miles is King Mountain, about 6,610 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Lower Paleozoic rocks, undivided (gneiss), from the Paleozoic to Mesozoic, 66 to 542 million years old.
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.
Granite. Age: Precambrian to Eocene. About 8 mi of the line.
Sand, gravel. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Gneiss. Age: Paleozoic to Mesozoic, 66 to 542 million years old. About 5 mi of the line.
Metasedimentary. Age: Devonian to Permian, 273 to 422 million years old. About 2 mi of the line.
Graywacke, quartzite. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Early Cambrian to Middle Ordovician, 459 to 542 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 Boyds reaches the Pacific Ocean by way of the Columbia: about 700 river miles.
Lake on the way: Lake Umatilla.
420 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Boyds; river miles along the main stem, rounded.
Boyds has a dry-summer warm-summer continental climate. Summer afternoons average 89° in August; winter nights fall to about 23° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Boyds normally reaches 44° and falls to 29°. The record high is 58°, in 2015; the record low 6°, in 1916. The most rain on this date, 0.59 in, fell in 1921.
Normals 1991–2020 and records since 1899 at Colville 5 NE, 18 miles east-southeast, 310 ft higher. NOAA, through RCC-ACIS.
