Capstone (rock formation)

A capstone, also known as a hoodoo or summit stone, is a large, naturally occurring rock that sits atop a hill, ridge, or other rock formation. Formed through geological processes like erosion and weathering, capstones act as protective coverings for the softer rock layers beneath them. They are often distinctive and prominent features in landscapes, symbolizing stability and endurance. Their durability results from their size, composition, and resistance to weathering compared to the underlying materials they shield. These formations can be visually striking and are important in understanding geological history and landscape evolution.
