Heart Mountain Relocation Center
6 miles southwest of Ralston

History
After the bombing of Pearl Harbor on December 7, 1941, many parts of the West Coast were declared military defense zones. The government ordered the removal of all persons of Japanese ancestry and the War Relocation Authority was established in March 1942 to house them in inland camps. The Heart Mountain Relocation center was one of ten temporary camps constructed to confine over 110,000 men, Wahington and part of Arizona. It was the only camp located in Wyoming. Construction on the center began in June 1942 and the first internees arrived in August of that year. At the peak of its population, the Heart Mountain Center, which covered over 740 acres, contained nearly 11,000 people housed in 450 barracks. Although surrounded by barbed wire and armed quards, the internees kept the camp functioning as a small city with its own public works, grade schools, a high school, hospital and newpaper. At the time it was the third largest city in Wyoming.

The camp was closed in November 1945, the buildings removed and the land, made arable by irrigation ditches completed by the internees, was opened up for homesteading.

A portion of the Heart Mountain Center was listed on the National Register of Historic Places on December19. 1985. The area listed includes the immediate vicinity of this Honor Roll and structures located to the east.
