Join Deer Isle resident, Dr. Norbert (Bert) E. Yankielun, P.E. former researcher for the U.S Army Cold
Regions Laboratory who specialized in sub-surface instrumentation research for a webinar presentation. This is a non-technical, and hopefully enlightening and entertaining presentation that examines the use of readily available, open-source, digital historical maps and imagery of Deer Isle to better visualize the terrain, environment, and cultural transformations that have historically occurred in our community from 1776 to present. After this presentation, you’ll never look at your local surroundings in the same way!
