84° on Nov. 16, 2011, the hottest reading for this week of the year since 1871. Next is 84° in 2024.
Bolivar Peninsula’s center stands about 9 ft above sea level. Within three miles the land runs from 0 ft to 10 ft, a difference of 10 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Barrier ridge and barrier flat deposts (sand), from the Holocene, less than 12,000 years old.
The section below crosses 3 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.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
