LROC NAC close-up of the wall of a suspected volcanic vent within the regional pyroclastic deposit near Sulpicius Gallus. Image M124505982R, view is 517 m across [NASA/GSFC/Arizona State University].

LROC NAC closeup of a small fresh crater (230 m across) with very dark ejecta within the regional pyroclastic deposit in the highlands near Rima Bode II. This site is near a NASA Constellation region of interest. This crater has excavated fresh pyroclastic material but has not penetrated through the deposit, which may be more than 100 meters thick in this area. LROC NAC image M124593116L. View is 478 m across [NASA/GSFC/Arizona State University].

LROC NAC closeup clustered craters on the Schrodinger pyroclastic cone, one of the NASA Constellation regions of interest. Although likely relatively young, the craters in this cluster have a subdued appearance because they formed in the loose pyroclastic material. NAC Frame M108313384R, view is 785 m across [NASA/GSFC/Arizona State University].

LROC NAC closeup of a fracture in the floor of Alphonsus crater. Dark pyroclastic materials are intermixed with lighter rocks and boulders from the fracture walls and all appear to have moved in streamers toward the fracture floor at upper right. A NASA Constellation site is centered just to the southeast of this view. Image width is 538 m, NAC image M111606491L [NASA/GSFC/Arizona State University].

NAC Frame M111945148R. Part of the vast pyroclastic deposit near a Constellation Program Region of Interest located on the Aristarchus plateau is visible in this image. View is 537 m across [NASA/GSFC/Arizona State University].
