RE: RE: RE: RE: WTR WTFI'm thinking a deeply incised limestone topography, subsiding slowly. The conditions required to make a 100m of coal would have to be stable for an extremely long time, or subsidence acting at essentially the same rate as bog-peat accumulation. Remember also that the highlands were the Shield area back then, and the ocean to the southwest. Judging possible coal ground based on the position of the present highlands (Pasquia Hills) would be incorrect. Glaciers have mostly "scooped" out the original base of the shield to flatland "contact". The best coal deposition area would likely be between the original highlands and the ocean.
Imagine how water would flood in to the Fraser Valley in BC over time if isostatic rebound did not equal the ocean water level increase due to glacial meltwater since the last Ice Age for a general idea od bog formation sites.
