Antelope Island Bioherm Flyover


The shallow waters of Bridger Bay, on the northwestern tip of Antelope Island in the southern arm of hypersaline Great Salt Lake, support extensive microbial carbonate formation, especially in the north-northeast portion of the bay near Egg Island.  Lake levels in the fall of 2014 were near 60-year lows (as low as 1278.1 m [4193.3 ft] AMSL, compared to the near-term historic average of about 1280 m [4200 ft]), giving unprecedented access to the microbial structures.  Characterizing the microbialites of Bridger Bay, including facies delineation and aerial extent, can inform interpretations of similar deposits in the ancient rock record (e.g., Eocene Green River Formation), including potential petroleum reservoirs.
