Historical Note

The United States Bureau of Land Management was formed in 1946 from the merger of the General Land Office and the United States Grazing Service. The Bureau of Land Management is in charge of administering over 245 million acres of public land, most of which is located throughout the 12 western states. The Bureau's mission is to sustain the health, diversity, and productivity of America's public lands for the use and enjoyment of present and future generations, which also includes managing the lands for energy development, livestock grazing, timber harvesting, and recreation. In Oregon, the western region is characterized by 2 million acres of checkerboard timberland ownership which is considered some of the most productive forests in the world, while the eastern Oregon portion of their ownership is known for large basin and range topography in semi-arid landscapes benefiting livestock grazing and range land habitat.

The Bureau of Land Management manages the Oregon and California Railroad Revested Lands (O&C Lands) in western Oregon. These lands (approximately 2.6 million acres) were originally granted to the Oregon & California Railroad for development of a railroad between Portland, Oregon, and San Francisco, California. The lands were reconveyed to the federal government in 1916 and have been managed by BLM since 1937.

Content Description

The Bureau of Land Management Maps of Oregon consist of maps published for use by the public as a guide for outdoor recreation as well as maps prepared for management and oversight of forest lands under the purview of the Bureau. The maps depict the boundaries of Bureau of Land Management (BLM) lands in Oregon, master units (primarily in western Oregon), and the extent of national forests. The master unit maps show the locations of O&C Lands, which are managed by the Bureau of Land Management. The maps in the collection range in scale from 1:125,000 to 1:1,000,000 and depict towns and cities, highways and major road systems, and major physiographic features. A 1981 map of wilderness areas in Oregon is also part of the collection.

Series III consists of 1:125,0000 scale (0.5 inch = 1 mile) maps of central and eastern Oregon produced by the Bureau of Land Management in the 1960s, many of which were corrected or updated in 1970.
