The Custer Battlefield National Monument is now the Little Bighorn Battlefield National Monument, and can be visited (virtually) at http://www.nps.gov/libi/

The nearby settlement of Garryowen (originally an administrative post for the Bureau of Indian Affairs) was named after the old Irish tune which was adopted as the 7th Cavalry's marching song, probably because there were many Irishmen serving in the 7th Cavalry at the time.
