5.70 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 4.56 inches, fell in 2023.
Holden Heights’s center stands about 100 ft above sea level. Within three miles the land runs from 80 ft to 130 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pleistocene to Holocene, less than 2.6 million years old.
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, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 20 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
