The principal, most widely recognized marker bed in the Wyoming sequence—the Alcova Limestone Member—has been correlated variously with many different parts of the Thaynes, as well as with beds considered younger than the Thaynes. Our studies indicate that the Alcova...

...Tohill Bruce; M. Dane Picard ABSTRACT In northwestern Wyoming the Crow Mountain Sandstone Member (Triassic) of the Chugwater Formation is underlain by either the Alcova Limestone Member or the sandy facies of the Red Peak Member. An unnamed redbed unit is locally disconformable on the Crow Mountain...

... of Liassic plesiosaurs. The structure of the limbs also shows advanced aquatic specialization, but not in the direction of plesiosaurian paddles. This conclusion agrees with stratigraphic evidence to suggest that the Alcova limestone is of late Triassic age. GeoRef, Copyright 2004, American Geological...

The alternations begin 20 to 75 ft below the base of the Alcova Limestone Member, and extend downward 200 to 425 ft in the sequence. This is 35...

We documented a detailed facies and fracture-intensity model using LIDAR-scanned outcrops located at the Alcova anticline in central Wyoming. Through this characterization, we reveal the existence of a striking variability in fracture intensity...
