3.43 inches of rain fell in two days, the most for this week of the year since records began in 1895. The next wettest, 2.75 inches, fell in 1903.
Hyner’s center stands about 700 ft above sea level. Within three miles the land runs from 610 ft to 2,140 ft, a difference of 1,530 ft: steep hill country. The highest named summit within 15 miles is Hyner Mountain, about 2,180 ft, 3 miles east.
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 3 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. Age: Devonian to Carboniferous, 324 to 422 million years old. About 17 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.

A raindrop that lands in Hyner reaches Chesapeake Bay and the Atlantic Ocean by way of Hyner Run, the West Branch Susquehanna and the Susquehanna: about 220 river miles.
Lake on the way: Lake Aldred.
90 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 Hyner; river miles along the main stem, rounded.
Hyner has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. A normal year brings about 33 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Hyner normally reaches 50° and falls to 32°. The record high is 72°, in 1902; the record low 14°, in 2019. The most rain on this date, 0.63 in, fell in 1997.
Normals 1991–2020 and records since 1895 at Renovo, 5 miles west. NOAA, through RCC-ACIS.
