3.50 inches of rain fell in two days, the most for this week of the year since records began in 1980. The next wettest, 3.44 inches, fell in 2011.
Gilbertsville’s center stands about 360 ft above sea level. Within three miles the land runs from 300 ft to 460 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Lewis Hill, about 620 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Alluvium (sand, silt), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Gravel, sand. Age: Tertiary to Holocene, less than 66 million years old. About 3 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 66 to 84 million years old. About 3 mi of the line.
Conglomerate. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Gilbertsville reaches the Gulf of America by way of Cypress Creek, the Tennessee, the Ohio and the Mississippi: about 1,040 river miles.

Gilbertsville has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Gilbertsville normally reaches 58° and falls to 37°. The record high is 77°, in 1999; the record low 13°, in 1986. The most rain on this date, 1.47 in, fell in 2024.
