Union Dale’s center stands about 1,720 ft above sea level. Within three miles the land runs from 1,340 ft to 2,280 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is North Knob, about 2,690 ft, 4 miles west.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 24 mi of the line.

A raindrop that lands in Union Dale reaches Chesapeake Bay and the Atlantic Ocean by way of the East Branch Lackawanna, the Lackawanna and the Susquehanna: about 250 river miles.
Lake on the way: Lake Aldred.
160 miles of the trip are on the Susquehanna.

Union Dale has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Union Dale normally reaches 45° and falls to 27°. The record high is 64°, in 1964; the record low 5°, in 1986. The most rain on this date, 1.30 in, fell in 1972.
