The Isle La Motte Preservation Trust presents this field trip in which participants learn about: the geological evolution of the Champlain Valley, the continental collision that developed the Adirondak Mountains about 1.3 billion years ago, and the quarries in the region - their importance and their rocks/ minerals. Why are these fossil-rich TROPICAL reefs in Northern Vermont and NY? Participants will meet at the ILM Rec Park, School St. for an introduction and then drive to Goodsell Ridge (<3 miles) to view the fossilized remains of the marine reefs including fossils of gastropods, cephalopods, stromatoporoids (extinct sponges), etc. Participants will learn how, when and where the tropical reefs were formed and how they ended up in Vermont. After a short walk, participants will learn about the development of the modern Lake Champlain Basin and its soils.

Suggested donation $10/person. All proceeds go to the Isle La Motte Preservation Trust.

Weather permitting. Dates: 7/9, 7/23, 8/6, and 9/3. Not offered 8/20/23.
