Keyhole Arch, Natural arch at Pfeiffer Beach, Big Sur, US
The sandstone formation features a large opening carved by ocean waves, creating a distinctive frame against the Pacific Ocean horizon point.
The geological structure formed over millions of years through continuous erosion of sedimentary rocks by powerful ocean currents and wind patterns.
Every winter, photographers gather at this location to capture the rare phenomenon of sunlight beaming through the arch during winter solstice.
Visitors can access the arch via Sycamore Canyon Road from Highway 1, with a parking fee of 12 dollars per vehicle at Pfeiffer Beach.
The arch produces a natural light show in December and January when the setting sun aligns perfectly, creating an orange beam through the opening.
