The Eldred 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.
76° on Nov. 11, 2020, the hottest reading for this week of the year since 1909. Next is 71° in 2012.
Eldred’s center stands about 1,440 ft above sea level. Within three miles the land runs from 1,430 ft to 2,180 ft, a difference of 750 ft: hilly country. The highest named summit within 15 miles is Clara Hill, about 2,470 ft, 12 miles east-southeast.
Under the town center the state geologic map shows Chadakoin Formation (siltstone, 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.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Sandstone, siltstone, shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 6 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Shale, sandstone. Age: Late Devonian to Carboniferous, 324 to 384 million years old. About 1 mi of the line.

A raindrop that lands in Eldred reaches the Gulf of America by way of Fowler Brook, the Allegheny, the Ohio and the Mississippi: about 2,220 river miles.
Lake on the way: Allegheny Reservoir.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eldred; river miles along the main stem, rounded.
Eldred has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. A normal year brings about 65 inches of snow; with the rain, that comes to about 41 inches of water.
