Beaches are the most dynamic places on Earth, offering an infinite variety of patterns and geological land formations. This book celebrates and solves the mysteries of the fascinating and frequently abstract beauty of gravitational effects at the water's edge. Lovers of natural history will appreciate the images of curiously sculpted potholes, towering sea stacks, sand and vegetal varieties, and blue sky reflected in striated rivulets, accompanied by diagrams and explanations of the natural forces at work. This book aims to enhance appreciation for oceans and their shape-shifting shorelines. They are, after all, wondrous.
