Twice a day, the Pacific Ocean leaves its mark in the sand on some Costa Rican beaches. As the tide goes out, it reveals designs of startling complexity and delicacy. Some resemble objects in nature; others are abstract enough to see in them whatever you will. Most people walk right by, but I discovered their beauty and have captured them in photographs I call “Impressions in the Sand``. Most people walk through life looking everywhere but down. ``Impressions in the Sand” comes from my stopping to see and appreciate the beauty that lies right at our feet.
