Hollansburg’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,090 ft to 1,240 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Hoosier Hill, about 1,320 ft, 3 miles west.
Under the town center the state geologic map shows Lockport Dolomite (dolostone), from the Silurian, 425 to 445 million years old.
The section below crosses 5 rock units mapped at the surface.

Dolostone. Age: Silurian, 425 to 445 million years old. About 10 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 5 mi of the line.
Limestone, shale. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Hollansburg reaches the Gulf of America by way of the Middle Fork East Fork Whitewater, the East Fork Whitewater, the Whitewater, the Great Miami, the Ohio and the Mississippi: about 1,540 river miles.
Lake on the way: Brookville Lake.
970 miles of the trip are on the Mississippi.

Hollansburg has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. About 40 inches of rain fall in a normal year.
On November 14 Hollansburg normally reaches 52° and falls to 33°. The record high is 74°, in 1909; the record low 7°, in 1986. The most rain on this date, 2.45 in, fell in 1993.
