Summary:
Overlies the Lava Dam Member of the Notch Peak Formation, which is one of three newly-named members of the Notch Peak in Millard Co, UT in the Great Basin province. Age changed from Late Cambrian and Early Ordovician to Early Ordovician age following usage of Hintze (1974). Earlier usage by Drewes and Palmer (1975) and by Whitebread (1969) included equivalents of Red Tops and Lava Dam Members of Notch Peak Formation of this report in the House, thus accounting for the older age assignment.
