Geology: This site is marked by a color anomaly which coincides with a diorite stock (Detterman and others, 1981; Cox and others 1981). The stock, dated at 32-40 million years, intrudes the Jurassic Naknek and the Eocene and Paleocene Tolstoi Formations (Detterman and others, 1981). The diorite is reported to be altered and to contain disseminated porphyry-type mineralization (MacKevett and Holloway, 1977). The main drainage in the area is anomalous in zinc (Cox and others, 1981). No mention is made of ore or gangue minerals.
Age: Tertiary.
Alteration: Color anomaly associated with diorite stock.
