A promontory is a high point of land that juts out into a body of water, such as an ocean, sea, or lake. These landforms are often characterized by steep cliffs and provide stunning views of the surrounding landscape. Promontories can be formed through various geological processes, including erosion and tectonic activity. Promontories are significant in navigation and coastal geography. They can serve as landmarks for sailors and are often home to unique ecosystems. Famous examples include Cape Cod in Massachusetts and Point Reyes in California, both of which attract tourists and nature enthusiasts.
