Within Geddes is a relatively large irregular depression, making it a pit-floor crater. Such pits are thought to be caused by volcanic activity.[2]

Hollows
Hollows are present on the floor of Geddes crater, mostly at the rims of smaller craters within it, and along the rim of the central depression.
The central depression of Geddes is irregular in shape and may be a collapse feature rather than an impact crater
