About this map

Crater Lake dominates this 1985 survey, which details the eastern shoreline and the volcanic geology of the caldera wall within Crater Lake National Park. The map documents numerous geological formations such as the Palisades, the Wineglass scree pattern, and the Pumice Castle. Water features like Cleetwood Cove include a Boat Landing and Gaging Station, illustrating the infrastructure used to monitor and access the lake.

South of the water, the terrain rises toward Dutton Ridge and the Anderson Bluffs, where headwaters for Lost Creek and Sand Creek originate. The eastern heights are punctuated by Scott Bluffs and a Lookout House near the park's interior peaks. This map serves as a record of the park's topography and specialized names just as it appeared in the mid-1980s, before modern digital mapping changed the way these volcanic features were cataloged.
