A cairn placed here in 1998 commemorates the Battle of Kapyong and recognizes the veterans and families connected to it. The battle was fought in Korea from April 22 to 25, 1951. The 2nd Battalion, Princess Patricia’s Canadian Light Infantry, helped prevent a potentially costly defeat; ten Canadians were killed and 23 wounded, and the battalion received the U.S. Presidential Unit Citation. Parks Canada holds a Kapyong anniversary ceremony here each April. The first ceremony in 1998 was the first time Canadian Korean War veterans could wear their Korean War medals on Canadian soil.
Radar Hill also hosted a radar station, but its precise operating period remains uncertain.
