Weeksville’s center stands about 2,440 ft above sea level. Within three miles the land runs from 2,410 ft to 5,000 ft, a difference of 2,590 ft: mountain country. The highest named summit within 15 miles is Baldy Mountain, about 7,460 ft, 10 miles northeast.
Under the town center the state geologic map shows Gravel, from the Pleistocene to Holocene, less than 1.8 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.
Quartzite, argillite, metasiltstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 14 mi of the line.
Age: Pleistocene to Holocene, less than 1.8 million years old. About 3 mi of the line.
Metasiltstone, argillite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.

A raindrop that lands in Weeksville reaches the Pacific Ocean by way of the Clark Fork, the Pend Oreille and the Columbia: about 940 river miles.
Lakes on the way: Lake Pend Oreille, Lake Umatilla and Noxon Rapids Reservoir.
460 miles of the trip are on the Columbia.

Weeksville has a warm-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Weeksville normally reaches 42° and falls to 30°. The record high is 60°, in 1999; the record low 5°, in 1959. The most rain on this date, 0.49 in, fell in 2021.
Normals 1991–2020 and records since 1956 at Thompson Falls Ph, 18 miles west-northwest. NOAA, through RCC-ACIS.
