|Location and accuracy||This site is at an elevation of about 400 feet on the left limit of a southeast-flowing creek that enters Icy Strait about 1 mile west of the mouth of Glacier Bay. The occurrence is about 2 miles west-southwest of the Alaska Chief prospect (MF077) and about 5.6 miles northwest of Pt. Carolus. It is located within about 0.2 mile. The occurrence is the same as number 30 of MacKevett and others (1971) and number 98 of Kimball and others (1978).|
Geologic descriptionThe mineral occurrence is within a large felsic granitic intrusion of Tertiary age (Brew and others, 1978). A representative sample from a 3-foot wide shear zone in the granite contained 7 ppm silver, 1500 ppm zinc, and 300 ppm lead (MacKevett and others, 1971, table 9).
