Over-the-Horizon Backscatter Radar Network, Christmas Valley Radar Site Transmit Sector Four Water Storage Tank, On unnamed road west of Lost Forest Road, Christmas Valley, Lake County, OR Contributor Names Historic American Engineering Record, creator Created / Published Documentation compiled after 1968 Subject Headings - Cold War - radar - radar tracking stations - military facilities - water tanks - Oregon -- Lake County -- Christmas Valley Notes - Significance: The Over-the-Horizon Backscatter radar network was an important physical and scientific product of the Cold War. From theories that had been conceived in the days of early long-distance radio transmissions, and building on over three decades of research into the subject, the network was a tremendous technological and military accomplishment. Although it was only starting operation as the Cold War was ending, the ability of a radar system to warn against low-flying aircraft at distances of up to 1,800 miles away was an amazing step forward in air defense. The water tank provides water related to the functioning of the facility. This structure is one of three water tanks located at Christmas Valley Radar Site, one at each transmit sector - Unprocessed Field note material exists for this structure: N1126 - Survey number: HAER OR-154-C Medium Photo(s): 1 Data Page(s): 3 Photo Caption Page(s): 1 Call Number/Physical Location HAER OR-154-C Source Collection Historic American Engineering Record (Library of Congress) Repository Library of Congress Prints and Photographs Division Washington, D.C. 20540 USA http://hdl.loc.gov/loc.pnp/pp.print Control Number or0554 Rights Advisory No known restrictions on images made by the U.S. Government; images copied from other sources may be restricted. http://www.loc.gov/rr/print/res/114_habs.html Online Format image pdf Description
