Antelope Island Bioherm Flyover
Utah Geological Survey geologist Michael Vanden Berg teamed up with individuals from Loma Linda University to fly a drone/GoPro over the microbialites/bioherms in the shallow waters of Great Salt Lake on the northwestern tip of Antelope Island.

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] above mean sea level, 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.
Flash Flood at Yellow Cat Wash
Utah Geological Survey paleontologists ran into a flash flood at Yellow Cat Wash as they were leaving the Stike’s dinosaur excavation. They had to wait about 3 hours before they felt confident they would get through safely.

Spot the Rock
To guess where this area is, look carefully at the water bubbling up and the rock formation surrounding it.

The correct answer is Crystal Geyser!
Crystal Geyser is located on the eastern bank of the Green River approximately 3.5 miles downstream from Interstate 70. It is a geologically unusual site to visit, as it is a cold-water, carbon-dioxide-driven geyser as opposed to the geothermal geysers you would see at Yellowstone.
In the past, Crystal Geyser’s eruptions were notably higher and more frequent than what they are today. As seen in the video the entire area is draped with beautiful travertine (calcium carbonate) which makes it a gem of a place to put on your bucket list.
