Washington’s center stands about 1,150 ft above sea level. Within three miles the land runs from 990 ft to 1,380 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Mosier Hill, about 1,510 ft, 9 miles west-southwest.
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 34×. 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, shale. Age: Permian, 252 to 299 million years old. About 10 mi of the line.
Sandstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 6 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 5 mi of the line.
Limestone, shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Washington reaches the Gulf of America by way of Catfish Creek, Chartiers Creek, the Ohio and the Mississippi: about 1,980 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Washington; river miles along the main stem, rounded.
Washington has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 22° in January. About 38 inches of rain fall in a normal year.
On November 14 Washington normally reaches 52° and falls to 36°. The record high is 74°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.10 in, fell in 1997.
Normals 1991–2020 and records since 1878 from the Wheeling Area threaded record (Wheeling Ohio County Airport, 21 miles west). NOAA, through RCC-ACIS.
