The Palmer 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. 14, 2025, the hottest reading for this week of the year since 1895. Next is 82° in 1999.
Palmer’s center stands about 1,800 ft above sea level. Within three miles the land runs from 1,710 ft to 1,830 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Mumpumpey Hill, about 1,970 ft, 13 miles southwest.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 16 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.5 mi of the line.

A raindrop that lands in Palmer reaches the Gulf of America by way of the Loup, the Platte, the Missouri and the Mississippi: about 1,920 river miles.
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 Palmer; river miles along the main stem, rounded.
Palmer has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 16° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 27 inches of water.
On November 14 Palmer normally reaches 52° and falls to 29°. The record high is 85°, in 2025; the record low −7°, in 1940. The most rain on this date, 0.75 in, fell in 1947.
