75° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 2012.
Austin’s center stands about 1,470 ft above sea level. Within three miles the land runs from 1,260 ft to 2,260 ft, a difference of 1,000 ft: steep hill country. The highest named summit within 15 miles is Lyon Hill, about 2,570 ft, 15 miles northeast.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. 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 12 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 10 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Austin reaches Chesapeake Bay and the Atlantic Ocean by way of Freeman Run, First Fork Sinnemahoning Creek, Sinnemahoning Creek, the West Branch Susquehanna and the Susquehanna: about 280 river miles.
Lake on the way: Lake Aldred.
110 miles of the trip are on the West Branch Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Austin; river miles along the main stem, rounded.
Austin has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 14° in January. A normal year brings about 55 inches of snow; with the rain, that comes to about 43 inches of water.
Normals 1991–2020 and records since 1948 at Port Allegany, 16 miles northwest. NOAA, through RCC-ACIS.
