Much has been written regarding the geologic position and the stratigraphic relations of the gypsum and associated strata which are present near Fort Dodge and many are the speculations which have been put forward to account for the peculiar conditions obtaining. Observers early discovered that the gypsum was not in conformable relationship with the underlying beds and later investigators, in order to account for this situation, have enlisted various agents, even faulting in a region so little subject to diastrophism as is Iowa, having been called upon to explain such unique phenomena as may be found in the gypsum area.
