Distal Margin of the Bacolor Crater Ejecta Layer

July 10, 2011
This observations shows the outer (distal) margin of the ejecta of Bacolor Crater. Ejecta (material thrown out of the crater) often simply fades out, becoming thinner as one looks further from the crater.

However, in some cases the ejecta has a flow-like edge, which might be related to subsurface water or ice being incorporated into the ejecta.
