NABSQNO 11S-419806-3716430. This unnamed sea natural arch has been eroded by wave action through a stack of volcanic tuff. It is located on the public beach near the southeast corner of Corona del Mar, Orange County, California. Access is usually only possible at low tide.
Vreeland listed this arch in his catalog as number 21-36 and reported a span of 15 feet. He mistakenly gave the name "Arch Rock" for this arch. This name actually applies to the arch he listed as 21-143, which is located about .4 miles to the northwest along the beach.
