This image covers part of the chaotic terrain in Masursky Crater, and was targeted due to evidence that ejecta from Mojave Crater—to the south—may have modified the landscape. Mojave Crater may be the most recent large (more than 50-kilometer wide) impact crater on Mars, and produced some remarkable fluvial (water-carved) landscapes.

In Masursky Crater we see huge numbers of boulder trails. These appear as dashed lines produced by boulders tumbling down steep slopes, periodically gouging troughs in the ground. Why are there so many boulder trails here? Possibly the ejecta from Mojave Crater disturbed the surface and sent the boulders tumbling downhill.
