2021 Map of Penobscot Lake

Evidence of the region's complex glacial geography is visible in the distribution of smaller water bodies like White Deer Pond and Lizzies Bog. The map traces the drainage patterns of Deadwater Brook and Penobscot Brook, which serve as the primary conduits for this high-country watershed. The United States of America Canada border cuts through the western section of the map, illustrating how political boundaries often bisect these continuous natural water systems such as those near Little Dingley Pond.
