C.O.D. seemed pretty convinced that the Gaptank is Canyon in age and not River. Suggested that Uddenthal might be Cisco equivalent and he said yes that was what the Jurassic pockets - to. He didn't know whether the #2 ls of King's might not also be Cisco also. The problem of the conglomerate pebbles in collection came up again. This is a good point - Ref. to Australia paper might be good here. C.O. Wants more collections from the upper Gaptank type locality, also a close study of the Wolfcamp and Udendental zone in that region.
