Crater Lake

The formations of the Cascade, Siskiyou, and Coastal Mountain ranges have shaped the southern Oregon region into what it is today. Its topography has influenced the distributions of local water resources while its rock strata and soils have determined the qualities and distributions of different plant communities. Together, these physical features have helped researchers and local governments draw land use zones for national forests, farmlands, and rural areas.

The George Duggar map collection contains over 100 maps of Oregon and California, ranging in date from 1863-2001. Contents include a topographic series created by the U.S. Geological Survey as well as land use planning and zoning maps by local city councils.

The Harry Smedes papers include maps, images, and reports of local geological studies conducted in Southern Oregon between 1956 and 1999. Areas of specific focus include topography, geologic hazards, volcanoes, earthquakes, and land use. The locations of rocks, minerals, and sediments are also included.

The Jeffrey M. Lalande papers include articles, reports, letters to the editor, and correspondence with Retired Forest Rangers. These materials concern controversies related to local and federal land use as well as land surveys for the Oregon Atlas. The papers also include Lalande's research and book documenting the explorations of Peter Skene Ogden. Ogden traveled through the Oregon-California borderlands in 1826-1827.

The Rogue River National Forest records include articles, reports, and maps on proclamations of land use, land-use plans, land surveys, and natural resource inventories in the Rogue River National Forest. The records also include images and letters. These materials were created between 1982 and 2011.
