Glauber is a small lunar crater that is located just to the north of the large walled plain Mendeleev,. This crater lies just outside the irregular rim of Mendeleev, but well within the outer skirt of ejecta. It is a circular crater with a rim that has not been significantly eroded. The simple inner walls slope down to a small floor at the midpoint with a peak at the center. (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.
