Use of the term, rimless, is to indicate no positive relief rim is present.
Erebus (330 m), Terra Nova (500 m, just east of Erebus), and Nimrod (600 m) not included because rover observations did not define
their morphometry. Endeavour (22 km) not included because it is older than the Burns Formation.

Use of the term, rimless, is to indicate no positive relief rim is present.

Included in Golombek et al. [2010]
Erebus (330 m), Terra Nova (500 m, just east of Erebus), and Nimrod (600 m) not included because rover observations did not define
their morphometry. Endeavour (22 km) not included because it is older than the Burns Formation.
