The U.S. National Park Service has awarded nearly $1 million in grants to increase public awareness about and help preserve sites related to the detention of Japanese-Americans during World War II.

The largest of the 19 grants, $282,000, is going to an organization that is building a museum at the former Heart Mountain Relocation Center outside Powell in northern Wyoming.

The U.S. government forcibly relocated and detained 110,000 Japanese-Americans at dozens of sites during World War II, including Heart Mountain, which held 11,000 Japanese-Americans at its peak in 1943.

Had the camp been a city, it would have been the fourth-largest in Wyoming at the time.

Also receiving grants are programs at the Manzanar and Tule Lake relocation centers in California; Honouliuli Internment Camp in Hawaii; Fort Lincoln Internment Camp in North Dakota; Kooskia Internment Camp in Idaho; Crystal City Internment Camp in Texas; and Central Utah (Topaz) Relocation Center.
