Pontoosuc and Colusa anchor this rural landscape in Hancock County, where the terrain is defined by a dense network of winding waterways. The northern reaches are carved by Spillman Creek and Opossum Creek, while the central and southern sections are drained by Camp Creek, Tilton Creek, and Grove Creek. This drainage pattern influenced the placement of early settlements and family cemeteries that dot the high ground between the draws.
