The Seth Ward 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.
86° on Nov. 16, 2025, the hottest reading for this week of the year since 1908. Next is 85° in 1956.
Seth Ward’s center stands about 3,370 ft above sea level. Within three miles the land runs from 3,350 ft to 3,400 ft, a difference of 50 ft: nearly flat ground.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Pleistocene, less than 2.6 million years old. About 23 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 1 mi of the line.

A raindrop that lands in Seth Ward reaches the Gulf of America by way of the White River, the Salt Fork Brazos and the Brazos: about 1,160 river miles.
Lakes on the way: Possum Kingdom Lake and Lake Granbury.
550 miles of the trip are on the Brazos.

Seth Ward has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 26° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Seth Ward normally reaches 62° and falls to 36°. The record high is 84°, in 2025; the record low 6°, in 1976. The most rain on this date, 0.83 in, fell in 2004.
