The unconformity between the Neoproterozoic and Cambrian in the southern Rocky Mountains occurs at the base of the Fort Mountain Formation. It records the start of a renewed transgressive phase in West Laurentia and the initiation of a stable passive margin. A completely new Upper Cambrian formational nomenclature is proposed for the southern Rocky Mountains of Alberta. The formations designated as Upper Cambrian are: Corona, and Mount Synge, Dresbachian; Bison Creek, Franconian; and the Mistaya, Trempealeauan. Two additional formations are referred to the Middle Cambrian sequence immediately underlying the Upper Cambrain; the . The Waterton Formation in the eastern Rocky Mountains and the lower part toward the northwest in the southern Rocky Mountains and southeastern Purcell Middle or Upper Cambrian, and. Formation (Upper Cambrian) and was divided into four informal members described by Dean (, ) and Ji and Barnes (). The Outram Formation ranges from to m thick within the Southern Rocky Mountains. The lower contact with the Sur-vey Peak Formation is gradational. The upper contact with the.

This unconformity, between the Hector Formation (Precambrian) and the Fort Mountain Formation (Cambrian), in the Rocky Mountains, is quite apparent and has been noted in numerous publications (to name a few,Walcott, ;Walcott, ;Sloss, ; Aitken, ; Young, ).
