You only question is how big is the swamp?

You have two factors, size of the swamp and extensiveness of the protective ridges.

Variance in coal seam thickness in the PRB to the south is about 8 times. So we can expect holes that vary from 12 feet to 100 feet for now.

Average in the Mannville is only 2 metres thick in other areas. Often however it is 5 metres.

I think they can hope for an upside of 8-9 metres of thereabouts in average thickness.
