These intersecting troughs, or fractures, cut across geologically young volcanic terrain in the Tharsis volcanic province. In many locations near where this image was taken, material has erupted from similar features.

However, it does not appear that material erupted from these particular fractures. Instead, they appear to crosscut material that flowed across the surface, indicating that the fractures are younger than the flows. The widths of the troughs at their rims are about 200 to 250 meters across.

This image is an example of how the surface can provide information about the processes happening in Mars’ interior.
