Beer is a circular, cup-shaped crater with a sharp-edged rim that has not been significantly eroded. The interior has a higher
albedo than the surrounding
lunar mare, which is usually an indication of a relatively young crater. A string of craters arc away from the rim to the southeast, which then grade into a straight rille, and were once known as Fossa Archimedes or Archimedes Rille, but now are officially unnamed.
The
mare to the east has a higher
albedo than the surrounding surface, and this lighter-
hued surface reaches to the base of the
Montes Archimedes. To the southeast of Beer is a
lunar dome that is of comparable diameter to the crater.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Beer.
