About this map

The Passadumkeag River system dominates this Penobscot County landscape, where the confluence of the E Br Passadumkeag River and W Br Passadumkeag River creates a complex network of wetlands and seasonal watercourses. The map reveals a highly distinctive geological formation at The Oxbow, reflecting the river's meandering path through the glacial lowlands. To the south, the massive One Thousand Acre Heath provides a significant example of Maine's inland peatland ecosystems, largely untouched by development.

Upland features such as Connecticut Ridge, Lombard Mtn, and Oak Mtn rise sharply from the basin, separated by a sparse network of logging roads and local connectors like Dirty Glove Rd and Treadwell Hill Rd. The eastern edge is defined by the deep waters of Lombard Lake and the northern reach of Upper Sysladobsis Lake, highlighting an area historically focused on timber management and remote recreation.
