Note book says 'same location as 6669.' This location and elevation was taken from Stebbins's notebook, however, he also made a label with different label information for 6669 that says: North Side of Mosquito Ridge, north of the Middle Fork of the American River. T14N, R12E, Section 30, elevation 3200 ft. The date on this label is 1 May 1968.)
