Newton Hamilton’s center stands about 550 ft above sea level. Within three miles the land runs from 510 ft to 1,950 ft, a difference of 1,440 ft: steep hill country. The highest named summit within 15 miles is Butler Knob, about 2,340 ft, 10 miles southwest.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Quartzite. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Black-shale. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 2 mi of the line.
Limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 10 smaller units along the line are not listed.

A raindrop that lands in Newton Hamilton reaches Chesapeake Bay and the Atlantic Ocean by way of the Juniata and the Susquehanna: about 160 river miles.
Lake on the way: Lake Aldred.
75 miles of the trip are on the Juniata.

Newton Hamilton has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 21° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Newton Hamilton normally reaches 53° and falls to 33°. The record high is 75°, in 1989; the record low 17°, in 1986. The most rain on this date, 0.72 in, fell in 1972.
Normals 1991–2020 and records since 1938 at Lewistown, 19 miles northeast. NOAA, through RCC-ACIS.
