Cedar Breaks National Monument

Videonummer 11939927
The Cedar Breaks amphitheatre in Utah is the remains of uplifted layers of sedimentary limestone and sandstone that once formed the bottom of an ancient lake. Over millions of years the lake dried up, the area was uplifted due to the forces of plate tectonics, and the rock was sculpted by wind and water. The vibrant colors are caused by impurities in the stone, including iron oxide. Some of the rock formations are called hoodoos which are columns that typically consist of relatively soft rock capped by harder less easily eroded stone that protects the spire beneath it. Hoodoos that form a thin wall are called fins. The amphitheatre is five kilometres wide with a depth of about 700 meters. It is part of the Grand Staircase, an immense sequence of exposed sedimentary rock layers that stretch two hundred kilometres in the American Southwest and feature some of the most dramatic scenery anywhere in the world.
