Layton’s center stands about 4,350 ft above sea level. Within three miles the land runs from 4,210 ft to 4,760 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Thurston Peak, about 9,650 ft, 6 miles east-northeast.
Under the town center the state geologic map shows Lake Bonneville deposits (clay), from the Pleistocene, less than 2.6 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 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Metamorphic. Age: Neoarchean to Paleoproterozoic, 1.6 to 2.8 billion years old. About 4 mi of the line.
Andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Peat. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Mudstone, conglomerate. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 0.4 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.
