Fault-Bounded Troughs

The large fault-bounded trough in the center of the image was nicknamed Gumby (after an animated cartoon figure) by Magellan scientists. Located in the Lavinia region at the intersection of two tectonic trends, Gumby measures 5 km (3 mi) wide and 100-200 m (.06 - .1 mi) deep. An example of one of the trends is the bright lines running E-W through Gumby's head. A second example is the bright lines running SW to NE through Gumby's legs and hips. The line of pits (by Gumby's elbow) suggests some igneous or volcanic activity may have accompanied the faulting.
