The Frazer plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
78° on Nov. 12, 1999, the hottest reading for this week of the year since 1956. Next is 68° in 2016.
Frazer’s center stands about 2,060 ft above sea level. Within three miles the land runs from 1,990 ft to 2,200 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Coal Hill, about 2,740 ft, 12 miles southwest.
Under the town center the state geologic map shows Alluvium (gravel, sand, silt), from the Pleistocene to Holocene, less than 1.8 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Cretaceous, 72 to 84 million years old. About 11 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 6 mi of the line.
Sandstone, shale, bentonite. Age: Late Cretaceous, 66 to 84 million years old. About 5 mi of the line.
Sandstone, siltstone, black-shale. Age: Late Cretaceous, 66 to 84 million years old. About 2 mi of the line.
Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 0.3 mi of the line.

A raindrop that lands in Frazer reaches the Gulf of America by way of Little Porcupine Creek, the Missouri and the Mississippi: about 2,910 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Sharpe and Lake Francis Case.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Frazer; river miles along the main stem, rounded.
Frazer has a cold semi-arid climate. Summer afternoons average 89° in July; winter nights fall to about 7° in January. About 14 inches of rain fall in a normal year.
On November 14 Frazer normally reaches 45° and falls to 24°. The record high is 68°, in 2016; the record low −8°, in 2014. The most rain on this date, 0.20 in, fell in 1995.
