The West Glendive 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.
77° on Nov. 13, 1999, the hottest reading for this week of the year since 1893. Next is 70° in 1989.
West Glendive’s center stands about 2,100 ft above sea level. Within three miles the land runs from 2,040 ft to 2,430 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Blue Mountain, about 2,940 ft, 13 miles southeast.
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 24×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, shale, bentonite. Age: Late Cretaceous, 66 to 84 million years old. About 7 mi of the line.
Sandstone, shale. Age: Early Paleocene to Middle Paleocene, 59 to 66 million years old. About 6 mi of the line.
Shale, siltstone, bentonite. Age: Early Paleocene, 62 to 66 million years old. About 5 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 3 mi of the line.
Age: Pleistocene to Holocene, less than 1.8 million years old. About 3 mi of the line.

A raindrop that lands in West Glendive reaches the Gulf of America by way of Dry Creek, the Yellowstone, the Missouri and the Mississippi: about 2,840 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.

West Glendive has a cold semi-arid climate. Summer afternoons average 88° in July; winter nights fall to about 9° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 West Glendive normally reaches 44° and falls to 24°. The record high is 67°, in 2016; the record low −13°, in 2014. The most rain on this date, 0.49 in, fell in 1964.
