This was recorded on a cloudy evening during an incoming tide on Gold Bluffs Beach in Prairie Creek Redwoods State Park, part of Redwood National and State Parks, which together are designated as a World Heritage Site and International Biosphere Reserve. The beach is broad with low dunes covered in tall grass, and backed by high bluffs and lush, temperate rainforest. A gentle breeze was blowing offshore from the dense forest atop the bluffs, across the grassy dunes, and out over the crashing waves. The steady roar of big surf breaking far out was accompanied by the crash of waves breaking on the shore, which ran up the beach and washed back down. I placed the microphone atop a grassy dune at the edge of the shore, beyond the reach of the rising tide. Recorded by Kelly Rafuse, in California, USA
