This image from NASA's Magellan spacecraft shows an area of dark volcanic lava flows overlying the brighter surrounding plains which are thought to have been formed from older flows.
This scene, which covers an area of 75 kilometers (46 miles) by 45 kilometers (28 miles), shows an area of dark volcanic lava flows overlying the brighter surrounding plains which are thought to have been formed from older flows. Some of the dark flows terminate on the narrow bright sinuous feature to the right of the image and it is assumed that they originate from eruptions at fissures located along this bright feature. The image is located at latitude 4.6 degrees North and longitude 331.8 East. The horizontal banding is a processing artifact in this photo made from the first orbit after the start of systematic mapping.
