A small crater sporting a healthy population of boulders and a higher reflectance surrounding ejecta blanket [LROC NAC M1120363462L, image width is 500 m [NASA/GSFC/Arizona State University].

Some boulders are exposed in an impact melt sheet. How can these boulders help geologists understand more about the timing of impact? LROC NAC M1120322807L, image width is 1600 m [NASA/GSFC/Arizona State University].

Debris flows on the slope of Benedict crater, note material that collected in small depressions. Boulders stand out as bright dots on the landscape. LROC NAC M112031488R, image width is 1200 m and downslope is to the upper right [NASA/GSFC/Arizona State University].

This unassuming textured surface surrounding a smooth tongue of material is likely a volcanic vent. LROC NAC M181495512L, image width is 1500 m [NASA/GSFC/Arizona State University].
