The Yankee Lake plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
73° on Nov. 12, 1949, the hottest reading for this week of the year since 1896. Next is 72° in 1931.
Yankee Lake’s center stands about 1,010 ft above sea level. Within three miles the land runs from 900 ft to 1,250 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Big Bend Hill, about 1,320 ft, 13 miles east.
Under the town center the state geologic map shows Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (shale, siltstone, sandstone), from the Devonian to Carboniferous, 324 to 422 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 7 mi of the line.
Siltstone, shale. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 0.6 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 0.6 mi of the line.

A raindrop that lands in Yankee Lake reaches the Gulf of America by way of Yankee Run, the Shenango, the Beaver, the Ohio and the Mississippi: about 1,980 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Yankee Lake; river miles along the main stem, rounded.
Yankee Lake 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 68 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Yankee Lake normally reaches 50° and falls to 34°. The record high is 69°, in 1994; the record low 12°, in 1986. The most rain on this date, 2.05 in, fell in 1993.
