Stratigraphy
Formation:Barton Beds
Stratigraphic resolution:bed
Stratigraphy comments: The Marchioness calls this Stratum 17 (numbered top to bottom), but she's including everying in the sequence. Based on a comparison with Bosma, 1974 Cray, 1973, it seems likely that this is part of the Barton Beds. This unit is about 20 ft in thickness
