The bright floor of the crater Lermontov, first imaged by Mariner 10, stands in contrast to the surrounding terrain of Mercury.

The bright floor of the crater Lermontov, first imaged by Mariner 10, stands in contrast to the surrounding terrain of Mercury. The large depressions found in the floor have been interpreted as evidence for explosive volcanism, providing insight into Mercury’s volcanic history. The surface within the crater also appears to have been altered by the formation of hollows.
