80° on Nov. 15, 1993, the hottest reading for this week of the year since 1967. Next is 75° in 1985.
Tioga’s center stands about 2,340 ft above sea level. Within three miles the land runs from 1,780 ft to 2,660 ft, a difference of 880 ft: hilly country. The highest named summit within 15 miles is Snakeden Mountain, about 3,870 ft, 14 miles southeast.
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 9×. 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. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Tioga reaches the Gulf of America by way of Strouds Creek, the Gauley, the Kanawha, the Ohio and the Mississippi: about 1,850 river miles.
Lake on the way: Summersville Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tioga; river miles along the main stem, rounded.
Tioga has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 21° in January. About 50 inches of rain fall in a normal year.
On November 14 Tioga normally reaches 54° and falls to 32°. The record high is 74°, in 1989; the record low 9°, in 1976. The most rain on this date, 0.82 in, fell in 1993.
Normals 1991–2020 and records since 1967 at Summersville Lake, 19 miles southwest, 570 ft lower. NOAA, through RCC-ACIS.
