Goosenecks are a type of river formation characterized by their winding, snake-like curves. They occur when a river meanders through a landscape, creating deep, narrow valleys. The term "gooseneck" is derived from the resemblance of these curves to the neck of a goose. One of the most famous examples is Goosenecks State Park in Utah, where the San Juan River has carved out a series of dramatic bends over millions of years. The park offers stunning views of the river's intricate patterns, showcasing the natural beauty of erosion and geological processes.
