Using the Mini-RF and LROC NAC instruments aboard LRO, we have characterized the distribution of cm- to m-scale boulders associated with the ejecta of several km-scale fresh lunar craters. The results of this work will lead to a means of determining the size distribution of ejected material from km-scale impact craters without having to gather statistics through counting features. It will also lead, more generally, to a better understanding of the cratering process. The unnamed fresh crater on the floor of Kopff crater offers a specific example (Figs. 1 and 2). Here we observe that ejecta from the fresh crater has been deposited beyond the rim of Kopff. With the wall of Kopff acting as a topographic obstacle (Fig. 3), we can use statistics on the boulder population to better constrain models of ejecta emplacement.
