Palmyra’s center stands about 860 ft above sea level. Within three miles the land runs from 780 ft to 1,030 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Lapham Hill, about 1,250 ft, 14 miles northeast.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 5 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.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 13 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 0.9 mi of the line.

A raindrop that lands in Palmyra reaches the Gulf of America by way of the Scuppernong, the Bark, the Rock River and the Mississippi: about 1,690 river miles.
Lake on the way: Lake Koshkonong.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Palmyra; river miles along the main stem, rounded.
Palmyra has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Palmyra normally reaches 46° and falls to 28°. The record high is 69°, in 1999; the record low 10°, in 1996. The most rain on this date, 0.45 in, fell in 2001.
Normals 1991–2020 and records since 1995 at Sullivan 3 SE - Wfo Mkx, 6 miles north-northeast. NOAA, through RCC-ACIS.
