The Beaverhill Lake Group is conformably overlain by the Cooking Lake Formation in eastern Alberta, and unconformably overlain by the Woodbend Formation west of the Leduc reef trend.
The base of the mountain, however, consists of Cape Granite and the two formations meet at a geological unconformity that is world-famous amongst earth scientists.
The age of the sequence ranges from Cenomanian through to Campanian, The upper boundary is an unconformity across which rocks of Maastrichtian to Paleocene age are missing.
The top of the sequence is an erosional unconformity to Pleistocene glacial gravels.
The Manitoba Group is conformably overlain by the Duperow Formation and disconformably overlays the Prairie Evaporite Formation or Winnipegosis Formation of the Elk Point Group.
The Alleghenian orogeny in North America (during the Carboniferous period) for example can be found as an angular unconformity between rock layers in large parts of that continent.
A Geodiversity audit of the site recorded pale to dark grey well bedded Carboniferous Limestone dipping consistently southwards with a small area of overlying horizontally bedded buff-coloured Jurassic oolitic limestone forming an angular unconformity.
