About this map

The settlement of Marion marks the southern reach of this Maine landscape, where the waters of Cathance Stream and Dennys River define the local drainage patterns. The topography is characterized by isolated peaks and glacial features, including Big Allan Mtn, Little Allan Mtn, and Porcupine Mtn, alongside the prominent ridge known as Whaleback. Water is the dominant geographic force here, represented by numerous river features like Stoddard Rips, Ayers Rips, and Gardner Rips, which indicate the fast-moving, rocky nature of the riverbeds.

Local transport is tied to the timber and recreation history of Washington County, evidenced by a network of ridge roads such as Smith Ridge Rd and E Ridge Rd. Notable wetlands and still waters, including Little Cathance Lake and Great Works Pond, are interspersed among the hills. This 2018 survey provides a clear view of how traditional land-use names like Shaw Meadow and Robinson Meadow persist in this sparsely populated interior region.
