The Mohole is a big hole in the southern Badlands. Mohole is originally used by the Ultor Corporation to extract massive quantities of resources from Mars. There's wreckage along the edge of the hole, which may be the colony of Redemption III, as many radio tags in the area have this name printed on them. By 2125, Parker is living in a shack located next to the Mohole.
- It may be named after Project Mohole, a real life project involving an attempt to drill into the Earth's crust to reach the mantle.
