3.62 inches of rain fell in two days, the most for this week of the year since records began in 1899. The next wettest, 3.27 inches, fell in 1992.
Crestline’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,110 ft to 1,270 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Ralston Knob, about 1,420 ft, 5 miles east.
Under the town center the state geologic map shows Sunbury Shale (black-shale), from the Carboniferous, 324 to 359 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 38×. 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: Devonian to Carboniferous, 324 to 422 million years old. About 10 mi of the line.
Black-shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Crestline reaches Lake Erie by way of Paramour Creek and the Sandusky: about 130 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crestline; river miles along the main stem, rounded.
Crestline has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Crestline normally reaches 50° and falls to 34°. The record high is 71°, in 1971; the record low 11°, in 1986. The most rain on this date, 3.11 in, fell in 1993.
Normals 1991–2020 and records since 1899 from the Mansfield Area threaded record (Mansfield Lahm Regional Airport, 12 miles east, 140 ft higher). NOAA, through RCC-ACIS.
