Abstract:
In northeastern Colorado the Pierre shale is divisible into three groups which can be carried into central Colorado. It is suggested for the present that Lower, Middle, and Upper Pierre might be sufficiently descriptive, but more definite nomenclature is justified. The name Hygiene is definitely associated with the Middle group. The distinct difference between the Lower and Upper groups also seems to justify greater distinction, and it is proposed that either a new name be applied to the Upper group or that the name Lewis shale be applied to its equivalent. If the name Lewis is applied to the upper shale member of the Pierre, the name Steele is suggested for the Lower group between the Hygiene group and the top of the Niobrara.
