67° on Nov. 11, 2005, the hottest reading for this week of the year since 1977. Next is 63° in 2016.
Evergreen’s center stands about 1,540 ft above sea level. Within three miles the land runs from 1,410 ft to 1,640 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Toad Mountain, about 1,760 ft, 8 miles north-northwest.
Under the town center the state geologic map shows Granite to granodiorite (granite, granodiorite), from the Neoarchean, 2.5 to 2.8 billion years old.
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 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 12 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 10 mi of the line.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
Gabbro, peridotite, pyroxenite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 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 Evergreen reaches Hudson Bay by way of Collett Creek, the Toad, the Otter Tail, the Red River of the North and the Nelson: about 1,320 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Otter Tail Lake, Big Pine Lake and Lake Winnipeg.
550 miles of the trip are on the Red River of the North.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Evergreen; river miles along the main stem, rounded.
Evergreen has a cold desert climate. Summer afternoons average 80° in July; winter nights fall to about −4° in January. Barely 0.0 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1977 at Tamarac Wildlife Ref, 17 miles northwest. NOAA, through RCC-ACIS.
