In the efforts to reinterpret these sandstones there has been some tendency to underestimate how varied they can be. Data from eight such shelf sandstone tongues (Campanian) in southeast Wyoming are used to illustrate how variable lowstand prograding wedges can be and how these should, in addition, be distinguished from forced-regressive wedges. The depositional environments encountered in these two types of wedges are surprisingly different, and the lowstand wedges, which are frequently tidally influenced, show a greater affinity with the overlying transgressive tract than with the preceding wave-dominated, forced-regressive shoreface deposits.
