<p>This was recorded on a calm and sunny winter afternoon on the beach below Smith Gulch on the Lost Coast in the King Range National Conservation Area, Humboldt County, California. </p><p>The tide was going out, so I set the mic up near the water in the intertidal zone at the border between an area of rocks and tide pools and a sandy stretch of beach. The sand was very coarse, almost tiny pebbles, and it made a pleasant sound as the waves washed up and down the beach. At the start of the recording the waves lapped at the shore only a few feet from the mic, but the tide receded quickly and by the end of this recording it was nearly twenty feet away.</p>
