The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Alteration Text: Pyroxenite Intrusive Has Been Sheared And Altered To Multiform Chlorite Schist And Subsequently Ankerized And Silicified. Chlorite Schist Sometimes Resembles Serpentine Schist Due To The Lusterous Green; In Places This Rock Has A Pseudomorphic Texture Much Like Serpentinized Peridotite But The Phenocrysts Instead Of Being Bastite Are Chlorite Embedded In A Fine-Grained Chlorite Matrix.

Comment (Deposit): NOT MUCH WORK DONE BEFORE 1896 WHEN EAGLE AND SHAWMUT CLAIMS WERE JOINED TOGETHER. REFERENCES INCLUDE REPORT ON EACH MINE SEPARATELY
Comment (Workings): CROSSCUT ADIT 1,100 FT. THROUGH FOOTWALL TO LODE AND CONNECTING WITH INCLINED SHAFT 2,163 FT., 19 LEVELS AT VARIOUS INTERVALS
Comment (Geology): GEOL.DESC: SLATE INTERBEDDED WITH THIN LAYERED SANDSTONE AVERAGING 2 INCHES; LENSES OF LIMESTONE 2 TO 3 FT. THICK OCCUR ABOVE VOLCANIC ROCKS AND THINNER LENSES OF CONGLOMERATE OCCUR IN SLATE BELOW THE VOLCANICS. BETWEEN GREEN-CHLORITE SCHIST AND BLACK SLATE A NARROW BELT OF PYROXENITE OR HORNBLENDITE OR AN ALLIED HORNBLENDE-PYROXENE PERIDOTITE EXISTS.
