Possible Impact Melt Deposits in a Multiple Impact Structure
ESP_062296_1840  Science Theme: Impact Processes
This image shows the eastern portion of a triple impact structure that is approximately 21 by 14 kilometers, visible in this Context Camera image.

In this close-up we can see possible impact melt-bearing deposits flowing from the higher elevation in the eastern portion of the crater into the larger central crater. In the eastern part of this image, where the topography is more level, the impact melt material appears to have ponded to form relatively dark and smooth deposits on the floor of the crater. The materials that were ejected outside of the crater, observed in the northeast section of this image, are much rougher in appearance.
