A relatively recent impact event distributed ejecta across the lunar surface. Smaller craters punch through the ejecta to reveal a darker substrate. LROC NAC M139782204LE, image width is 500 m [NASA/GSFC/Arizona State University].

A small crater hides a bench of bedrock within its walls. Boulders sit just outside the rim. LROC NAC M1624467033R, image width is 800 m [NASA/GSFC/Arizona State University].

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].

Impact crater exhibiting boulders clustered off center, the crater also has a poorly defined rim. What could be the cause of these distinctive features? LROC NAC M1117124706L, image width is 900 m [NASA/GSFC/Arizona State University].

Fifty meter diameter crater with a bright ejecta blanket that extends several crater radii. The darker interior of the crater could be a melt pond. Image width is 1000 m, LROC NAC M1117189620R [NASA/GSFC/Arizona State University].

Normal faults in regolith formed graben in Numerov crater. Only a handful of small craters superpose the faults, indicating a young age. LROC NAC M171619370RE, image width is 600 m [NASA/GSFC/Arizona State University].

A complex wrinkle ridge in Mare Crisium at low Sun (illumination is from the right). Boulders occupy the tops of mounds on the west ridge, and the central depression is more heavily cratered than the ridge. LROC NAC M146573730RE, image width is 700 m, north is up [NASA/GSFC/Arizona State University].
