Shuckburgh lies south-southeast of the flooded crater Chevallier and northwest of Hooke, roughly mid-way between these two formations. The interior floor of this crater has been resurfaced with lava, leaving a level plain surrounded by the worn and rounded outer rim. This floor is nearly featureless, being marked only by a few tiny craterlets. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
