Oblique view of landslides in Ophir Chasm,Mars,computer-processed from Viking spacecraft imagery & topographic maps of the planet. Ophir Chasm lies in the central region of the giant Martian canyon system the Valles Marineris. The canyons were formed by a combination of geological faulting,landslides,& erosion by wind & water. The three arc-shaped cliffs at right are slump scarps and the landslide debris is piled at the base of the cliffs. The scarps are each about 25 km wide and 4 km high and the landslide debris has flowed a distance of about 65 km from the cliff base. The vertical scale of the image has been stretched by a factor of 2,exaggerating the cliff heights. (Image processing by Alfred McEwen & topographic mapping by Sherman Wu,both at USGS,Flagstaff | |
