The museum in the South Dakota Cultural Heritage Center in Pierre is open Monday, May 27, for the Memorial Day holiday from 1-4:30 p.m. CDT.

All other offices of the South Dakota State Historical Society in the Cultural Heritage Center, including the archives research room, are closed on Monday.

The museum is open this Saturday from 9 a.m.-4:30 p.m., and Sunday from 1-4:30 p.m.

Starting Tuesday, May 27, and running through Labor Day in September, the museum will be open extended hours – Monday-Saturday from 9 a.m.-6:30 p.m. and Sundays and holidays from 1-4:30 p.m.

“We hope people take advantage of the extra hours and visit the museum in the Cultural Heritage Center,” said Jay D. Vogt, director of the South Dakota State Historical Society. “We’re sure it will be a memorable and educational experience for people of all ages.”

Two new exhibits are featured in the museum this summer. “Transformation & Continuity in Lakota Culture: The Collages of Arthur Amiotte, 1988-2014” displays the colorful artwork of the Lakota artist in the Hogen Gallery. “South Dakota Environments: A Window to Past Times” is in the Observation Gallery and features four epochs of environmental history about the land that eventually became South Dakota and the animals found on the land.

Museum admission is free for children 17 and younger; there is a small fee for adults ages 18 and older.

Public hours for the archives research room remain unchanged -- 9 a.m.-4:30 p.m. Monday-Friday and the first Saturday of each month.
