77° on Nov. 16, 1928, the hottest reading for this week of the year since 1895. Next is 72° in 1902.
Anthony’s center stands about 720 ft above sea level. Within three miles the land runs from 530 ft to 1,210 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Huckleberry Mountain, about 2,590 ft, 15 miles north-northeast.
Under the town center the state geologic map shows Hamilton Group (black-shale), from the Early Devonian to Middle Devonian, 384 to 422 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. 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 10 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Black-shale. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 4 mi of the line.
Limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 3 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Anthony reaches Chesapeake Bay and the Atlantic Ocean by way of West Branch Chillisquaque Creek, Chillisquaque Creek, the West Branch Susquehanna and the Susquehanna: about 160 river miles.
Lake on the way: Lake Aldred.
85 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Anthony; river miles along the main stem, rounded.
Anthony has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 20° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Anthony normally reaches 51° and falls to 34°. The record high is 69°, in 1989; the record low 13°, in 1986. The most rain on this date, 1.53 in, fell in 1972.
Normals 1991–2020 and records since 1895 from the Williamsport Area threaded record (Williamsport Regional Airport, 15 miles west-northwest, 200 ft lower). NOAA, through RCC-ACIS.
