Birt is a lunar impact crater that is located in the eastern half of the Mare Nubium. To the east of the crater is the Rupes Recta, a long, linear feature commonly called the "Straight Wall". In actually this is only a slight rise in the surface of the mare with a maximum height of about 240 meters. It has a width of about 2.5 kilometers and is 100 kilometers in length.
The Birt crater is a bowl-shaped formation with a raised rim. It is slightly intersected along the southeast rim by the much smaller crater 'Birt A'. To the west of Birt, a rille named Rima Birt runs north-northwest in an arc from 'Birt F' to 'Birt E'.

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 Birt crater.
