The top of the member is marked by 60 to 100 m of thin-bedded calcareous quartzite and quartz arenite. Interfingers with the upper part of the Beck Spring Dolomite; locally unconformably overlies the Beck Spring Dolomite, Crystal Spring Formation, and older Proterozoic rocks; underlies the Surprise Member of the Kingston Peak Formation. Thickness ranges from 50 to 500 m. Age is Proterozoic. (B1565)
