You Won’t Believe What Lies Beneath Puerto Rico’s Sand: Hidden Secrets Beneath the Sea Puerto Rico, renowned for its turquoise waters and stunning beaches, hides a surprising story beneath its sandy shores—one filled with ancient mysteries, striking geological wonders, and untold secrets waiting to be uncovered. While the island captivates visitors with its breathtaking coastlines, what lies beneath Puerto Rico’s sand is far more fascinating than most ever imagine. ### The Hidden Depths of Puerto Rico’s Subsurface Beneath the sparkling surface of Puerto Rico’s beaches lies a complex geological tapestry shaped by millions of years of tectonic shifts, volcanic activity, and sedimentation processes. The island sits at the boundary of the Caribbean Plate and the North American Plate, a dynamic zone where underwater faults and volcanic formations lie hidden deep beneath the ocean floor. Scientific studies reveal ancient lava flows, sediment layers rich in fossils, and even submerged caves formed during past ice ages when sea levels were much lower.
