Gosport’s center stands about 680 ft above sea level. Within three miles the land runs from 550 ft to 770 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Moser Hill, about 990 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Sanders Group (limestone), from the Carboniferous, 324 to 359 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 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Siltstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.5 mi of the line.

A raindrop that lands in Gosport reaches the Gulf of America by way of Limestone Creek, the White River, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,350 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gosport; river miles along the main stem, rounded.
Gosport has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Gosport normally reaches 53° and falls to 32°. The record high is 78°, in 1955; the record low 4°, in 2019. The most rain on this date, 3.40 in, fell in 1993.
Normals 1991–2020 and records since 1922 at Martinsville 2 SW, 12 miles east-northeast. NOAA, through RCC-ACIS.
