Geologic Map of Addison County

Thank you to everyone who wished me a happy birthday. Above is a geologic map I made of Addison County, Vermont based on another map, illustrated by Charles G. Doll (of the Vermont Geological Survey), that resides in my school's science hall. Here, the different colors represent the ages of the county's *underlying rock, with black outlines showing the current borders of local communities - including towns, the city of Vergennes, and census-designated places.
