Avalanche captured from Mars orbit by NASA's Mars Reconnaissance Orbiter (MRO) spacecraft
Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.
When they reach the bottom of the more than 500 meter tall cliff face, the blocks kick up a cloud of dust. The layers beneath are different colors and textures depending on the amount of dust mixed with ice.
Imagery captured 318.2 km (197.8 miles) above the planet's surface
Black and white images are 5 km across; enhanced color images are 1 km.
