New investigations of the geology of Crater Lake National Park necessitate a reinterpretation of the eruptive history of Mount Mazama and of the formation of Crater Lake caldera. Mount Mazama consisted of a glaciated complex of overlapping shields and stratovolcanoes, each of which was probably active for a comparatively short interval.

2000 Multibeam sonar survey of Crater Lake, Oregon - Data, GIS, images, and movies
In the summer of 2000, the U.S. Geological Survey, Pacific Seafloor Mapping Project in cooperation with the National Park Service, and the Center for Coastal and Ocean Mapping, University of New Hampshire used a state-of-the-art multibeam sonar system to collect high-resolution bathymetry and calibrated, co-registered acoustic backscatter to support both biological and geological research in the CAuthorsJames V. Gardner, Peter DartnellByFilter Total Items: 17Water balance for Crater Lake, Oregon
A water balance for Crater Lake, Oregon, is calculated using measured lake levels and precipitation data measured at Park Headquarters and at a gage on the North Rim. Total water supply to the lake from precipitation and inflow from the crater walls is found to be 224 cm/y over the area of the lake. The ratio between water supply to the lake and precipitation at Park Headquarters is calculated asAuthorsManuel NathensonTemperatures of springs in the vicinity of Crater Lake, Oregon, in relation to air and ground temperatures

The basin floor of Crater Lake (10-km diameter, 600-m water depth) is covered by up to 75 m of sediment–gravity-flow deposits interbedded with mud. In the upper units (8 m (thick), sand and gravel layers with numerous wedging, strong seismic reflectors characterize the base-of-slope aprons at the basin margin. These layers evolve to turbidites of mainly thin, fine-grained, basin-plain type, characAuthorsC.H. Nelson, A.W. Meyer, D. Thor, M. LarsenByLithic breccia and ignimbrite erupted during the collapse of Crater Lake Caldera, Oregon
The climactic eruption of Mount Mazama (6845 y.B.P.) vented a total of ∼50 km3 of compositionally zoned rhyodacitic to basaltic magma from: (a) a single vent as a Plinian pumice fall deposit and the overlying Wineglass Welded Tuff, and (b) ring vents as ignimbrite and coignimbrite lithic breccia accompanying the collapse of Crater Lake caldera. New field and grain-size data for the ring-vent produAuthorsT. H. Druitt, C. R. BaconEruptive history of Mount Mazama and Crater Lake Caldera, Cascade Range, U.S.A.

Mapping the National Parks
The national parks of the United States are often compared to, and indeed inspire, works of art. In fact, the USGS has been regularly contributing new and updated works of art for the national parks—maps. - Partners
