Camden — Coastal Mountains Land Trust and the Camden Public Library will co-host an online Zoom presentation, From the Neck Down: A Geologic Ramble around the Fernald’s Neck Preserve, at 6 p.m. Thursday, Sept. 9.

The presentation on the geology of Fernald’s Neck Preserve will be led by D. Brooks McKinney, Emeritus Professor of Geoscience at Hobart and William Smith. Fernald’s Neck is a popular preserve and visitors who explore its trails and shoreline will encounter a variety of rocks and geologic features that underlie the Neck. This introductory presentation will give participants a checklist of geologic observations they can make during their own visits to the preserve and explain how the features they see connect to the complicated 500-million-year-old geologic history of Midcoast Maine. No prior knowledge of geology is necessary and there will be time for questions after the presentation.

A current resident of Belfast, Brooks got interested in rocks and minerals in 1968 after discovering a book in his local public library called “Your Future in Geology.” One thing led to another: a bachelor’s degree in geology from Beloit College, three years of work in Utah and Nevada as an exploration geologist, a doctorate from Johns Hopkins University, a geology teaching career at Hobart and William Smith Colleges, retirement and Emeritus status in June 2018.
