2018 Map of Vulcans Throne

About this map

Grand Canyon National Park dominates this terrain where the Colorado River carves through the landscape below the Aubrey Cliffs. The topographic survey highlights the striking verticality of the region, from the high desert floor of Prospect Valley to the dramatic volcanic landform of Vulcans Throne. This cinder cone overlooks the canyon near Lava Falls, a renowned rapid on the river. The map details the transition from the wide Toroweap Valley to the narrow, steep-walled gorges of Saddle Horse Canyon and Cove Canyon. Further south, the landscape levels into the Esplanade Bench before dropping into Prospect Canyon. Remote water sources such as Hogan Spring, Honda Springs, and Toroweap Lake provide critical points of reference in this arid environment, while the boundary between Mohave and Coconino counties follows the jagged path of the river and canyon rim.
