Hopewell’s center stands about 1,410 ft above sea level. Within three miles the land runs from 900 ft to 2,280 ft, a difference of 1,380 ft: steep hill country. The highest named summit within 15 miles is Kinton Knob, about 2,560 ft, 14 miles west-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 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 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.
Shale. Age: Silurian, 422 to 445 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 Hopewell reaches Chesapeake Bay and the Atlantic Ocean by way of Yellow Creek, the Raystown Branch Juniata, the Juniata and the Susquehanna: about 230 river miles.
Lakes on the way: Lake Aldred and Raystown Lake.
90 miles of the trip are on the Juniata.

Hopewell has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 21° in January. About 37 inches of rain fall in a normal year.
On November 14 Hopewell normally reaches 51° and falls to 34°. The record high is 73°, in 1993; the record low 11°, in 1986. The most rain on this date, 2.25 in, fell in 1972.
Normals 1991–2020 and records since 1948 at Altoona Blair County Airport, 13 miles north. NOAA, through RCC-ACIS.
