Comments on the geologic information

  • Geologic Description = This site is a large color anomaly that extends approximately 5,000 feet north-south and 1,000 to 2,000 feet east-west. The map site is at the south end of the anomaly. The anomaly marks altered, pyrite-bearing, diorite, volcanic, and epiclastic rocks (Christie, 1974) mapped as Miocene volcanic rocks (Wilson and others, 1995). The anomaly is cut off to the east by the sea; some of the system is probably under water.
  • Age = Miocene or younger.
