Possible Lunar Lava Tube Skylights

Possible Lava Tube Skylights Discovered Near the North Pole of the Moon

"The pits were identified through analysis of imaging data from NASA's Lunar Reconnaissance Orbiter (LRO). If water ice is present, these potential lava tube entrances or "skylights" might allow future explorers easier access to subsurface ice, and therefore water, than if they had to excavate the gritty ice-rich "regolith" (surface rubble) at the actual lunar poles."
