Crater Lake National Park Maps, 1903-1962

Historical Note:

Crater Lake National Park is a majestic landmark and Oregon's only National Park. Crater Lake formed about 7,700 years ago when a volcanic eruption destroyed Mount Mazama leaving a 2,148 foot deep caldera in its place. This caldera filled through the ages forming the present 1,943 foot deep lake, which remains the deepest lake in the United States. This lake and surrounding area was established as a National Park primarily through the efforts of William Gladstone Steel, who first saw the lake in 1885 and began mapping it extensively in 1886 with Clarence Dutton for the U.S. Geological Survey. In 1893, Crater Lake became part of the Cascade Range Forest Reserve. However, Steel continued to advocate and Crater Lake National Park was established in May 1902.

John V. Byrne joined the faculty of Oregon State University in 1960 as an Associate Professor of Marine Geology. He was appointed chair of the Oceanography Department in 1968 and subsequently served as the first Dean of the School of Oceanography, the Dean of Research, and President of Oregon State University (1984-1995).
