Ancient 'lava falls' on Mars

Molten rock once flowed along a crater rim in Mars’ Tharsis volcanic province, creating stunning multi-level ‘lava’ falls. A breathtaking image captured by NASA’s Mars Reconnaissance Orbiter reveals the incredible structures left behind, in a region reminiscent of Niagara Falls.

The photo shows a glimpse at the northern rim of a 19-mile-wide (30 kilometer) crater, with evidence that a lava flow once surrounded the region until it breached at four separate locations, to cascade down the walls.

The experts say the lava came in from the north-northeast around the crater rim – and when it got high enough, it breached the rim in four places. Three of the falls, in the north-central region of the crater wall, can be seen in the image. The photo shows a glimpse at the northern rim of a 19-mile-wide (30 kilometer) crater
