Announcing the 2018 BYU Geological Sciences Alumni Field Trip!
Geology of the Great Salt Lake
The 2018 alumni field trip features the geology of the Great Salt Lake and takes place on Saturday, October 13th. It will be led by Tom Chidsey, Bob Lindsay, Peter Nielsen, and Mike Vanden Berg. The first stop is Antelope Island to look at Lake Bonneville shorelines, oolitic beaches, and modern “microbialites” with a mini core workshop to compare them with microbialite cores from the Eocene Green River Formation of the Uinta Basin. Then it’s on to Promontory Point and an approved drive across the Lake’s railroad causeway to observe pink water, salt crusts/polygons, and microbialite domes. The final stop features Pleistocene microbialite reefs and tufa mounds. We will be wading around the briny water on a couple of stops so bring rubber boots like the ones in the photos (they should be around $10) or there will be a limited amount available (first come first serve).
Lunch, snacks, and drinks are provided. There is no cost for the trip but donations to the department to support students are appreciated. We look forward to your participation.
Participants meet at the BYU Museum of Paleontology (1683 N Canyon Road, Provo) at 7AM Saturday October 13th. Vans depart at 7:30. We will be back at BYU at about 6:30 PM.
