Summary:

At the Sideling Hill road cut, the unit believed to be the Patton Shale by Bjerstedt (1986) is present between two thick sandstone units, the upper assigned to the Purslane Sandstone and the lower to the Rockwell Formation. The contact between the two units is here redefined. The intervening shale, is assigned to the overlying Purslane Sandstone in this report. The term Patton Shale Member of Rockwell Formation (of Bjerstedt, 1986) is not used.
