About this map

Crater Lake National Park occupies the heart of this survey, dominated by the western half of the massive caldera and its iconic central feature, Wizard Island. The map details the intricate geology of the rim, highlighting distinctive formations such as the Devils Backbone and the towering Llao Rock. The landscape is a network of modern recreation and ancient volcanic remnants, where the Pacific Crest National Scenic Trail traverses the western slopes far below The Watchman.

Notable features include the Witches Cauldron atop the island and the deep incisions of the Munson Valley to the south. The map documents numerous spring-fed drainage systems, including Lightning Spring and the headwaters of the Copeland Cr forks, which flow outward from the high volcanic plateau. Cultural routes like the Rim Trail and Llaos Hallway demonstrate how the park’s unique topography has been interpreted and accessed in the twenty-first century.
