This report covers the collections made by Jim Ratte and Warren Hamilton last summer. Examination of the corals by Bill Oliver may give more definitive ages on some of these collections. Two of the collections of Ratte (74ARa68B, 68C) are probably Early Cretaceous and have been sent to Dave Jones for study. Collections retained.
