The Haivana Nakya 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.
94° on Nov. 12, 1967, the hottest reading for this week of the year since 1942. Next is 93° in 1999.
Haivana Nakya’s center stands about 2,860 ft above sea level. Within three miles the land runs from 2,750 ft to 3,490 ft, a difference of 740 ft: hilly country. The highest named summit within 15 miles is Quinlan Mountains, about 6,830 ft, 7 miles east-southeast.
Under the town center the state geologic map shows Quaternary surficial deposits, undivided (sand, silt, clay), from the Pleistocene to Holocene, less than 2 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Diorite, alkali-granite, granodiorite. Age: Early Jurassic to Late Jurassic, 150 to 180 million years old. About 12 mi of the line.
Arenite, conglomerate. Age: Late Jurassic to Late Cretaceous, 80 to 160 million years old. About 3 mi of the line.
Sandstone, siltstone, conglomerate. Age: Middle Jurassic to Late Jurassic, 150 to 170 million years old. About 3 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2 million years old. About 3 mi of the line.
Gravel, sand. Age: Late Pliocene to Pleistocene, 0.8 to 3 million years old. About 3 mi of the line.
Granite. Age: Late Cretaceous to Early Eocene, 50 to 80 million years old. About 2 mi of the line.

Haivana Nakya has a hot desert climate. Summer afternoons average 99° in June; winter nights fall to about 33° in December. Barely 0.0 inches of rain fall in a normal year.
On November 14 Haivana Nakya normally reaches 75° and falls to 40°. The record high is 91°, in 1999; the record low 22°, in 2018. The most rain on this date, 0.65 in, fell in 1968.
