The Bandon plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
21° on Nov. 13, 1978, the coldest reading for this week of the year since 1897. Next is 27° in 1985.
Bandon’s center stands about 70 ft above sea level. Within three miles the land runs from 0 ft to 320 ft, a difference of 320 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Bennett Butte, about 2,160 ft, 13 miles 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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Paleocene to Early Eocene, 48 to 66 million years old. About 6 mi of the line.
Gravel, boulders, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 5 mi of the line.
Mudstone, sandstone. Age: Late Jurassic to Late Cretaceous, 66 to 164 million years old. About 2 mi of the line.

A raindrop that lands in Bandon reaches the Pacific Ocean by way of the Coquille: about 1 river miles.
