Summary of data on the age of the Orca Group, Alaska: A section in <i>The United States Geological Survey in Alaska: Accomplishments during 1984</i>

“…The lower age range of the unit is not k1own but is probably Paleocene as it postdates the Maestrichtian Valdez Group. The age relation~hip of the strata at Jeanie Point and Neck Point en Montague Island to the remainder of the Orca Gro'tf) is uncertain, but these strata most probably have shared the same deformational and metamorphic history as the remainder of the Orca Group (Dumoulin and Miller, 1984).…”
