Out of the Shadows: Impact Melt Flow at Byrgius A Crater
Spectacularly preserved viscous flow on the NE rim of Byrgius A (19 km diameter) crater. This flow has a form similar to lava flows on the Earth - however it formed as a result of an asteroid or comet slamming into the Moon at...

Epigenes A
A plethora of boulders surrounds braided flows of impact melt along the inside wall of crater Epigenes A. As the melt moves toward the crater floor (direction indicated by white arrow), the flow buries and moves boulders. Epigenes A is...

A Very Sinuous Rille
Two oxbow bends along the length of a sinuous rille located on a mare-filled crater floor. The tight twists and turns of the rille suggest that a very turbulent lava flow formed this rille. Subarea of uncalibrated LROC NAC frame...
