Alum Bluff Expedition

Postponed. New date TBD

Harley Means, Assistant State Geologist, will lead an expedition to Alum Bluff, a classic geological exposure located along the east bank of the Apalachicola River approximately 1.8 miles north of the town of Bristol in Liberty County, Florida. Alum Bluff is the tallest natural exposure in Florida, and is famous for the fossil molluscan faunas contained in some of the strata. Additionally, there are plant and occasional vertebrate fossils known from this locality. During low stages of the Apalachicola River approximately 125 feet of vertical exposure can be observed, making it possible to collect fossils. We will meet at the Harry Donar Boat Landing in Bristol, Florida at 9:30am EDT to boat up the Apalachicola River. The boat and life jackets for adults will be provided by the Florida Geological Survey. (If you are bringing a child, please provide an appropriate life jacket.) Those who wish to carpool can meet at 8:00am EDT in the Walmart parking lot at 4400 West Tennessee Street. From the Bristol Boat Landing, we will motor up the river to learn about the exposed units and collect fossils. Wear clothing and shoes appropriate for wet, muddy conditions and bring collecting bags and tools as desired. We will return to the boat landing at approximately noon. This field trip is weather dependent, as high river levels will not allow for good viewing of the exposure. We will post and email updates as to the status of the trip the week prior. We will also email information about carpooling closer to the fieldtrip. The trip will be limited to 20 TSS members.
