Hudson Crossroads’s center stands about 1,220 ft above sea level. Within three miles the land runs from 1,000 ft to 1,680 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Mill Mountain, about 3,300 ft, 14 miles north-northeast.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 7 mi of the line.
Limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 3 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.

A raindrop that lands in Hudson Crossroads reaches Chesapeake Bay and the Atlantic Ocean by way of Crooked Run, Mill Creek, the North Fork Shenandoah, the Shenandoah and the Potomac: about 300 river miles.
180 miles of the trip are on the Potomac.

Hudson Crossroads has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 21° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Hudson Crossroads normally reaches 57° and falls to 32°. The record high is 79°, in 1955; the record low 6°, in 1986. The most rain on this date, 1.30 in, fell in 1972.
