5.32 inches of rain fell in two days, the most for this week of the year since records began in 1941. The next wettest, 3.38 inches, fell in 1952.
University of California-Santa Barbara’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 350 ft, a difference of 350 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Little Pine Mountain, about 4,470 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Older Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene, less than 2.6 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.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 3 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Sandstone, mudstone. Age: Eocene to Miocene, 5.3 to 56 million years old. About 0.7 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.5 mi of the line.
