The Cedar Mountain extends over a long duration of the Early Cretaceous, and
into the earliest Late Cretaceous.

The basalmost part, the Yellow Cat Member, is Barremian.  The next two
(Poison Strip and Ruby Ranch Members) are Aptian-Albian.  The Mussentuchit
Member hugs the Albian (latest Early K) and Cenomanian (earliest Late K)
boundary.
