George Circling Eagle has made it his life's mission to unveil the largely untold stories of the black Wild West. A traveling speaker from New Jersey, Circling Eagle uses slides and quotes to illuminate historical facts about the black Wild West as well as tales his grandmother told him as a child. Circling Eagle, whose roots are Apache, Cherokee, African American and Mohawk, brings to life stories about black explorers, pioneers, cowboys and Indians. His presentation covers the 24 all-black towns that arose in Oklahoma between 1890 and 1900, black cowpunchers on the Chisolm Trail and the Buffalo Soldiers of the U.S. Cavalry. In conjunction with Native American History Month, the Upper Marlboro Community Center presents Circling Eagle for its "Black West" discussion at 7 p.m. Wednesday. The event is free, but reservations are required. The center is at 5400 Marlboro Race Track Rd., Upper Marlboro. 301-627-2828.
