The Bowman 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.
3.25 inches of rain fell in two days, the most for this week of the year since records began in 1891. The next wettest, 2.81 inches, fell in 1976.
Bowman’s center stands about 790 ft above sea level. Within three miles the land runs from 590 ft to 830 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Sillimanite Schist/ Gneiss (schist, gneiss), from the Precambrian to Paleozoic.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, gneiss, amphibolite. Age: Precambrian to Paleozoic. About 7 mi of the line.
Granite. Age: Precambrian to Paleozoic. About 6 mi of the line.
Schist, gneiss. Age: Precambrian to Paleozoic. About 4 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Bowman reaches the Atlantic Ocean by way of Beaverdam Creek and the Savannah: about 300 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bowman; river miles along the main stem, rounded.
Bowman has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 30° in January. About 49 inches of rain fall in a normal year.
On November 14 Bowman normally reaches 64° and falls to 37°. The record high is 79°, in 1964; the record low 18°, in 1963. The most rain on this date, 1.90 in, fell in 1972.
