The Barrow trail member of the Schrader Bluff Formation.

This unit is overlain by a yellowish brown weathering very fine sandstone/siltstone approximately 3 m thick. Above this is a platy yellowish gray fine sandstone with a relatively depauperate fauna of inoceramids and bivalves. Low angle to hummocky cross stratification. This is overlain by a dark bioturbated mudstone with fine sands associated with flaser bedding grading into a light gray very fine sandstone with large inoceramids.
