Lava flows

Lava flows

. This Magellan image shows a lava-filled canyon produced when Venusís crust was pulled apart and magma rose within the gap. The lowland plainss contain many similar canyon systems, typically about 10 thousand meters wide and up to 1000 thousand meters long, apparently filled with solidified lava flow. This region, located near the equator between Asteria Regio and Phoebe Regio, is about 10 thousand meters wide and stretches 600 thousand meters to the north (top). (Courtesy of JPL and NASA.)
