74° on Nov. 12, 1999, the hottest reading for this week of the year since 1956. Next is 62° in 1976.
Haugan’s center stands about 3,130 ft above sea level. Within three miles the land runs from 3,050 ft to 5,030 ft, a difference of 1,980 ft: steep hill country. The highest named summit within 15 miles is Cherry Peak, about 7,340 ft, 13 miles northeast.
The section below crosses 4 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.
Quartzite, argillite, metasiltstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 13 mi of the line.
Quartzite, metasiltstone, argillite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Metasiltstone, quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Sedimentary. Age: Tertiary, 2.6 to 66 million years old. About 1 mi of the line.

A raindrop that lands in Haugan reaches the Pacific Ocean by way of the Saint Regis, the Clark Fork, the Pend Oreille and the Columbia: about 1,000 river miles.
Lakes on the way: Lake Pend Oreille, Lake Umatilla and Noxon Rapids Reservoir.
460 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Haugan; river miles along the main stem, rounded.
Haugan 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 Haugan 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, 15 miles north, 750 ft lower. NOAA, through RCC-ACIS.
