The National Park Service's "Corps II" traveling exhibits and programs will be at Fort Mandan in Washburn Friday through Monday for the final Lewis and Clark Bicentennial event in North Dakota.

Hosted by the Lewis and Clark Fort Mandan Foundation, Corps II and its "Tent of Many Voices" presents free public programs from 10 a.m. to 5 p.m. each day in Fahlgren Park, adjacent to the Headwaters Fort Mandan Visitor Center.

"These free events are a great way for us to wrap up this three-year celebration," says Foundation Executive Director Kristie Frieze. "A great variety of presenters will present the expedition story from a number of perspectives, with special emphasis on tribal voices."

Among those presenters is Landon Jones, author of "William Clark and the Shaping of the West," who will be in the tent at 2 p.m. Saturday. He will sign books in the visitor center afterward.

Other authors during the event include Teri Evenson, "Cooking with Lewis & Clark," at 1 p.m. Saturday; Jeff Evanson, "Art of the Lewis & Clark Expedition," at 2 p.m. Saturday; and Tracy Potter, "Sheheke: Mandan Indian Diplomat," at 1 p.m. Sunday.

Other presenters include interpretive staff from Fort Mandan, the Knife River Indian Villages and Cross Ranch State Park, along with tribal historians from the region.

An added attraction at the Lewis and Clark Interpretive Center is the exhibit "An American Family: The William Clark Family Collection," featuring more than 100 artifacts on loan from Peyton Clark, William's great-great-great grandson.

All of the Corps II programs are free, with admission to Fort Mandan and the Lewis and Clark Interpretive Center ($7.50 for adults and $5 for students). Foundation members get in free.
