When hundreds or thousands of coral polyps build their skeletons close together, they create a calcium carbonate structure that provides habitat and food for a variety of organisms. This is known as a coral reef. Explore a virtual coral reef. More Info - Common Coral Forms; More Info - Fringing Reefs
Arch Cape is an unincorporated community in Clatsop County, Oregon, United States. It is located along the Pacific coast about 4 miles south of Cannon Beach. The Arch Cape post office, established in 1912, has ZIP code 97102. The community was named for a natural arch in the coastal rocks.
It was given its current name by Frank Beckwith, leader of the Arches National Monument Scientific Expedition, who explored the area in the winter of 1933â1934. Although there is a rumor that the names of Delicate Arch and Landscape Arch were inadvertently exchanged due to a signage mixup by the National Park Service [NPS], this is false.
