Barringer is a lunar impact crater on the southern hemisphere on the far side. It is attached to the north-northeastern rim of the walled basin named Apollo, and lies to the southeast of Plummer. South , on the floor of the Apollo basin, is the crater Scobee. This crater is generally circular in form, with a slight outward bulge along the western rim. (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.
