Plainview Formation

The formation overlies the Lytle Formation and is overlain by the Glencairn Formation and comprises resistant, brown-weathered sandstones, and dark shales and siilstones, also described as bioturbated brownish sandstones with black and grey silty or shaley sandstone intervals. The formation was deposited in a variety of near-shore and/or marginal marine environments. The tracks occur in the upper part of an estuarine point bar sequence, overlain by brackish bay or lagoon deposits.^[1]
