An outcropping of the Anastasia Formation seen along the shoreline of Blowing Rocks Preserve at low tide. Blowing Rocks Preserve is an environmental preserve on Jupiter Island in Hobe Sound, Martin County, Florida, USA. Breaking waves spray plumes of water through erosion holes; the spray can reach heights of 50 feet (15 m). This distinctive spectacle thus earned the limestone outcrop's name. The limestone outcropping also encompasses coquina shells, crustaceans, and sand. As one of the most beautiful beach locations in South Florida, it's perfect for engagement sessions, bridal portrait sessions, maternity photography session, fashion, swimsuit and even boudoir photography assignments. The best time to get to Blowing Rocks preserve is early in the morning to capture the sun as it rises over the horizon for even more dramatic photos.
