About this map

The Shinumo Amphitheater dominates this dramatic landscape, where the naming conventions reflect an era of romanticism in geographical exploration. The terrain is marked by prominent landforms such as King Arthur Castle, Guinevere Castle, and Elaine Castle, which rise above the deep fractures of Merlin Abyss and Modred Abyss. This map documents a complex drainage system within Grand Canyon National Park, centered on the perennial flow of Shinumo Creek and its tributary White Creek.

Upland features include the Powell Plateau and Swamp Ridge, which separate the deep canyon systems from the forested heights of the Kaibab National Forest. Evidence of natural water sources is scattered across the higher elevations, including Upper Two Spring and the curiously named Swamp Lake. The presence of the Gila and Salt River Meridian provides a primary reference for the early surveying of this northern Arizona territory.
