A Huge Volcanic Eruption
This giant pit, 20 kilometers (12.4 miles) wide and 2 kilometers (1.2 miles) deep, was formed by a massive, explosive volcanic eruption. The ash deposits blown from the crater may be rich in hydrogen, helium, iron, and titanium. They not only provide a glimpse into the composition of the lunar interior, but also could serve as resources for future lunar explorers.
