The Bishop Hills 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.
85° on Nov. 16, 2021, the hottest reading for this week of the year since 1892. Next is 85° in 2025.
Bishop Hills’s center stands about 3,530 ft above sea level. Within three miles the land runs from 3,340 ft to 3,710 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Goat Mountain, about 3,770 ft, 6 miles west.
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 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.
Siltstone-mudstone. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 8 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 8 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 5 mi of the line.
Conglomerate-sandstone. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 1 mi of the line.
Sandstone-mudstone. Age: Permian, 252 to 299 million years old. About 0.6 mi of the line.
Clay, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Bishop Hills reaches the Gulf of America by way of West Amarillo Creek, the Canadian, the Arkansas and the Mississippi: about 1,580 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Bishop Hills has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 25° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Bishop Hills normally reaches 62° and falls to 34°. The record high is 85°, in 2025; the record low 5°, in 1916. The most rain on this date, 1.09 in, fell in 1924.
