About this map

Marion sits near the southern edge of this landscape, where local roads like Marion Rd and Stage Rd converge in Washington County. This inland terrain is defined by a complex network of waterways, including the Dennys River and its various tributaries. Several distinct water features, such as Gardner Rips, Ayers Rips, and Stoddard Rips, indicate a river system with significant elevation changes and rapid water flow through the timberlands.

Elevations rise to several prominent peaks, including Big Allan Mtn, Little Allan Mtn, and Porcupine Mtn. To the west, Little Cathance Lake feeds into the Cathance Stream, while the southeastern corner is occupied by the expansive Great Works Pond. The distribution of roads, such as Ayers Junction Rd and Dodge Rd, suggests a landscape shaped by rural transport and forestry access between established peaks and valleys.
