74° on Nov. 13, 1999, the hottest reading for this week of the year since 1906. Next is 70° in 1934.
Hill View Heights’s center stands about 4,330 ft above sea level. Within three miles the land runs from 4,150 ft to 4,840 ft, a difference of 690 ft: hilly country. The highest named summit within 15 miles is Mount Pisgah, about 6,410 ft, 12 miles north.
Under the town center the state geologic map shows Greenhorn Formation and Belle Fourche and Mowry Shale, from the Early Cretaceous to Late Cretaceous, 66 to 145 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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 78 million years old. About 8 mi of the line.
Sandstone, siltstone, shale. Age: Late Pennsylvanian to Permian, 273 to 307 million years old. About 4 mi of the line.
Sandstone, claystone. Age: Late Jurassic to Early Cretaceous, 100 to 164 million years old. About 2 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Limestone, shale. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million 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. 6 smaller units along the line are not listed.

A raindrop that lands in Hill View Heights reaches the Gulf of America by way of Stockade Beaver Creek, Beaver Creek, the Cheyenne, the Missouri and the Mississippi: about 2,660 river miles.
Lakes on the way: Lake Oahe, Lake Sharpe, Lake Francis Case and Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.

Hill View Heights has a cold semi-arid climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 17 inches of water.
On November 14 Hill View Heights normally reaches 46° and falls to 25°. The record high is 74°, in 1999; the record low −11°, in 1955. The most rain on this date, 0.51 in, fell in 1927.
