75° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 68° in 2005.
Elk Creek’s center stands about 1,180 ft above sea level. Within three miles the land runs from 960 ft to 1,330 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Gibson Hill, about 1,600 ft, 7 miles east-southeast.
Under the town center the state geologic map shows Berea Sandstone through Venango Formation, undivided (shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 5 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.
Shale. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Siltstone, shale. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 0.9 mi of the line.

Elk Creek straddles the St. Lawrence Divide. Rain on the southeast side runs to the Gulf of America; most of the rest goes to Lake Erie.
From the center of town, a raindrop reaches Lake Erie by way of Temple Creek, East Branch Conneaut Creek and Conneaut Creek: about 45 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic. One that lands on the southeast side reaches the Gulf of America by way of West Branch Cussewago Creek, Cussewago Creek, French Creek, the Allegheny, the Ohio and the Mississippi: about 2,130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Elk Creek; river miles along the main stem, rounded.
Elk Creek has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 17° in January. A normal year brings about 111 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Elk Creek normally reaches 48° and falls to 33°. The record high is 67°, in 2010; the record low 17°, in 1996. The most rain on this date, 0.53 in, fell in 2021.
Normals 1991–2020 and records since 1996 at Springboro 3 WNW, 8 miles southwest, 180 ft lower. NOAA, through RCC-ACIS.
