The title here refers to a phenomenon all too familiar on the north coast. On a day with seemingly small surf there appears out of nowhere a set of large powerful waves. This can be dangerous for the unwitting beachcomber. As the surfers always say "Never turn your back on the surf!" This oil painting is 18 x 58. It features the gallery wrap. Recently sold through Studio Kokomo in Calistoga, CA. in the beautiful Napa Valley.
