It was deposited in a nearshore environment, unconformably overlying Precambrian basement.[1] It is overlain by the Eau Claire Formation or Ordovician strata. It is presumed to be Upper Cambrian in age, though not verified.[2] See infobox for more details.[3] The Mount Simon formation is the equivalent of the La Motte Sandstone formation in the St. Francois Mountains of Missouri.[3] References1. ^{{cite report|last1=Hamblin|first1=A.
