White Canyon


This image of White Canyon, Utah, from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft shows a kind of terrain on Earth known as karst topography, which occurs when water dissolves layers of bedrock, leaving dramatic rock outcroppings and sinkholes. An area on Saturn's moon Titan called Sikun Labyrinthus displays some similar characteristics. The simulated natural color image of White Canyon was obtained Oct. 2, 2008.
