Wahak Hotrontk’s center stands about 1,940 ft above sea level. Within three miles the land runs from 1,900 ft to 2,050 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Quijotoa Mountains, about 3,900 ft, 13 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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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, silt, clay. Age: Pleistocene to Holocene, less than 2 million years old. About 18 mi of the line.
Gravel, sand. Age: Late Pliocene to Pleistocene, 0.8 to 3 million years old. About 1 mi of the line.
Conglomerate, sandstone. Age: Early Oligocene to Late Miocene, 11 to 32 million years old. About 1 mi of the line.
Sandstone, siltstone, conglomerate. Age: Middle Jurassic to Late Jurassic, 150 to 170 million years old. About 1 mi of the line.
Arenite, conglomerate. Age: Late Jurassic to Late Cretaceous, 80 to 160 million years old. About 1 mi of the line.
Granite. Age: Late Cretaceous to Early Eocene, 50 to 80 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
