7.68 inches of rain fell in two days, the most for this week of the year since records began in 1905. The next wettest, 6.40 inches, fell in 1941.
Port Orford’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 550 ft, a difference of 550 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Panther Mountain, about 3,300 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Terrace, pediment, and lag gravels (gravel, boulders, clay), from the Pleistocene to Holocene, 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 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
