2023 Map of Marengo

About this map

Marengo Hills dominate the central topography of this Adams County landscape, where the winding course of Cow Creek carves through the basalt-rich terrain of the Inland Northwest. The map captures a high-desert environment defined by scattered agricultural outposts and the long-distance corridor of the Palouse To Cascades State Park Trl. This trail follows the historic path of the former Chicago, Milwaukee, St. Paul and Pacific Railroad, connecting small, isolated settlements that reflect the area's rail-dependent heritage. Small population centers like Marengo and Carlmar are joined by the remote locations of Teske and Emden, which once served as vital nodes for grain transport. The grid of rural roads, including Harder Rd and Cow Creek Rd, underscores the persistence of ranching and dryland farming in a region shaped by ice-age floods and pioneer-era expansion.
