is the
Lava -flooded
Crater located on the southwestern shore of the
Mare Nectaris on
Earth's Moon . It lies to the northwest of the similarly-flooded
Fracastorius Crater remnant. To the west is the prominent
Catharina Crater .
The rim of Beaumont crater is breached in the east, where the lava from
Mare Nectaris broached the crater and flooded the interior. Now only a worn and crater-impacted outer wall remains. If the crater once possessed a central peak, it is no longer apparent. The floor contains several hills and small craters. A low ridge runs northward from the crater rim across the
Mare Nectaris .
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Beaumont crater.
