Dinosaur National Monument defines this river landscape where the Green River and Yampa River meet. The confluence occurs at Echo Park, a point of significant topographical change overlooked by the massive profile of Steamboat Rock. This survey records the complex drainage systems of the eastern Plateau, including Whirlpool Canyon and the southern reach of the Canyon of Lodore. Named landmarks such as Jenny Lind Rock and Outlaw Arch sit alongside historical references to early resource exploration, noted by Iron Mine Ridge and Iron Mine Draw. The map documents a network of isolated meadows and flats like Box Elder Park and Menlo Park, connected by the Echo Park Trail, providing a clear view of the canyon floor access before modern landscape changes. High-altitude features like Wild Mtn and the Ant Hills mark the transition from river bottom to the high desert ridges.
