77° on Nov. 13, 1999, the hottest reading for this week of the year since 1915. Next is 71° in 1953.
Rhame’s center stands about 3,210 ft above sea level. Within three miles the land runs from 3,010 ft to 3,310 ft, a difference of 300 ft: rolling country.
Under the town center the state geologic map shows Slope Formation (sandstone, siltstone, claystone), from the Paleocene, 56 to 66 million 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 34×. 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, siltstone, claystone. Age: Paleocene, 56 to 66 million years old. About 12 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 6 mi of the line.
Sandstone, siltstone, claystone. Age: Paleocene, 56 to 66 million years old. About 4 mi of the line.
Sandstone, siltstone, claystone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.

A raindrop that lands in Rhame reaches the Gulf of America by way of Spring Creek, Coyote Creek, the Little Missouri, the Missouri and the Mississippi: about 2,940 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 Rhame; river miles along the main stem, rounded.
Rhame has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 6° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 17 inches of water.
On November 14 Rhame normally reaches 41° and falls to 19°. The record high is 71°, in 1953; the record low −16°, in 2014. The most rain on this date, 0.54 in, fell in 1928.
Normals 1991–2020 and records since 1915 at Bowman, 14 miles east-southeast, 230 ft lower. NOAA, through RCC-ACIS.
