AC&W Sq was inactivated on 1 November 1983 and the station redesignated as a Long Range Radar (LRR) Site. In 1990, jurisdiction of the Indian Mountain LRR Site was transferred to Pacific Air Forces (PACAF)'s Eleventh Air Force with the redesignation of AAC. In 1998 PACAF initiated "Operation Clean Sweep", in which abandoned Cold War stations in Alaska were remediated and the land restored to its previous state. After years of neglect the facilities at the station had lost any value they had when the site was closed. The site remediation of the radar, support and White Alice communication station was carried out by the 611th Civil Engineering Squadron at Elmendorf AFB, and remediation work was completed by 2005. Today very little of the former Cape Lisburne Air Force Station remains. Demographics Cape Lisburne (Station) was listed on the 1970 and 1980 U.S. Censuses. It was made a census-designated place (CDP) in 1980. With the closure of the station in 1983, it ceased to appear on the census. Distant Early Warning Line support Beginning in July 1957, Cape Lisburne AFS controlled a sector of the Distant Early Warning Line. The LIZ sector was the most westernmost point of the network, composed of a series of surveillance radar stations along the northwest Alaska Coast to Icy Cape (LIZ-B), about 140 miles to the northeast. Cape Lisburne controlled five manned stations, two of them being classified as "Auxiliary" sites and three "Intermediate" stations. The Auxiliary stations were similar to the main site at Cape Lisburne; the Intermediate sites having less personnel at them. The stations were made up of an AN/FPS-19 search radar, a high power L-Band radar consisting of two identical radar sets feeding a dual (back to back) antenna with a range of about 160 nautical miles. The sites had one 25-man module building for personnel who supported the radar, and an airstrip, although the length and capacity varied greatly, making frequent risky landings necessary at some sites. Each of the sites were staffed by civilian contract workers who had signed 18-month contracts, although they were visited by Air Force military personnel from Cape Lisburne frequently. With the signing of North American Air Defence Modernization agreement at the "Shamrock Summit" between Prime Minister Mulroney and President Reagan in Quebec City on 18 March 1985, the DEW Line began its eventual upgrading and transition becoming the North Warning System (NWS) of
