Brief statement of problem and remarks (from collector):
Fossils from light-colored and dark-colored carbonates which normally would be considered typical facies of the Lisburne. However, the base of the dark facies cuts out more than 10 feet of the light making it unconformable and, to some extent, seems gradational, through glauconitic beds, into overlying Siksikpuk. Coral and brach determinded ages should verify or preclude significance of the discordance.
