The Happy 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.
87° on Nov. 16, 2025, the hottest reading for this week of the year since 1947. Next is 85° in 1967.
Happy’s center stands about 3,600 ft above sea level. Within three miles the land runs from 3,560 ft to 3,680 ft, a difference of 120 ft: gently rolling country.
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 54×. 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.
Clay, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.8 mi of the line.

A raindrop that lands in Happy reaches the Gulf of America by way of the Prairie Dog Town Fork Red, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,330 river miles.
1,040 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Happy; river miles along the main stem, rounded.
Happy has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 22° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Happy normally reaches 61° and falls to 32°. The record high is 84°, in 2025; the record low 9°, in 1976. The most rain on this date, 0.81 in, fell in 2004.
