The presence of fresh water fish, plant debris, and thin pedogenic carbonate layers suggests that the fine-grained beds were deposited in a lacustrine environment; however, the presence of thin horizons with glauconite grains, marine-affinity bivalves, arenaceous foraminifera, and one specimen of a trilobite (Weir 2002; Tibert and Scott 1999) suggest a distal marine influence (Martel and Gibling 1996; Ryan 1998; Tibert and Scott 1999).
