Tamaqua’s center stands about 1,310 ft above sea level. Within three miles the land runs from 770 ft to 1,600 ft, a difference of 830 ft: hilly country. The highest named summit within 15 miles is Bears Head, about 2,090 ft, 9 miles west-northwest.
Under the town center the state geologic map shows Llewellyn Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Shale, slate. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Siltstone, sandstone. Age: Late Devonian, 359 to 384 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. 7 smaller units along the line are not listed.

A raindrop that lands in Tamaqua reaches Delaware Bay and the Atlantic Ocean by way of Panther Creek, the Little Schuylkill, the Schuylkill and the Delaware: about 190 river miles.
100 miles of the trip are on the Schuylkill.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tamaqua; river miles along the main stem, rounded.
Tamaqua has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 19° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 52 inches of water.
Normals 1991–2020 and records since 1934 at Lehighton 1 SSW, 12 miles east, 860 ft lower. NOAA, through RCC-ACIS.
