Midwest Traveler: Beyond the Corn Palace in Mitchell, S.D.

If there's a holy trinity of South Dakota photos for Minnesotans road-tripping west, it usually involves a silly pose at Wall Drug atop a giant jackalope, the must-see presidents of Mount Rushmore, and Mitchell's famed Corn Palace.

Less than five hours from the Twin Cities, the Corn Palace is a welcome place to stop and stretch your legs, take a bathroom break and shoot selfies. But there's much more to this Taj Mahal of folk art than a schmaltzy photo op. And there's more to Mitchell than the Corn Palace, including an ongoing excavation of a prehistoric village and vibrant art and pioneer history displays in its Dakota Discovery Museum.

At the Corn Palace, artists can be seen each summer creating almost a dozen new murals on what could be dubbed the world's funkiest bird feeder. Themes and murals have changed every year since the palace was built in 1892, encompassing everything from space exploration and nursery rhymes to sports to patriotism. This year's historic scenes commemorate South Dakota's 125th year of statehood using 12 colors and more than 275,000 ears of corn, plus 3,000 bushels of grains such as oats, sorghum and rye for accents.

Inside the palace, free tours and a 15-minute film tell about other agricultural-themed palaces from America's era of grand spectacles, dreamed up by fledging communities eager to draw more businesses and farmers.

"The World's Only Corn Palace" has endured for more than 120 years and still attracts up to 500,000 visitors a year. It doubles as a sports and concert venue, and has added hands-on exhibits about corn. Kids climb into a combine and try virtually harvesting a field, while others gawk at a towering mound of products made from corn.

The palace is undergoing a $7.2 million makeover that will redesign the onion-like turrets and add more lighting, wind turbines and an outdoor balcony for visitors to see one of the Midwest's most iconic free attractions more closely.

With a perfect blue summer sky as a backdrop, it remains a stellar spot for a classically corny vacation photo, but leave time to look around and learn more.

Wesleyan is also home to the free McGovern Legacy Museum, highlighting the life of former U.S. senator and presidential candidate George McGovern and his wife, Eleanor, from their college years here through World War II and into the 1970s.

Prehistoric Village: Archaeology buffs can geek out on the northern edge of Mitchell, where scientists estimate a village of about 80 earth lodges thrived more than 1,100 years ago. See displays of a typical earth lodge, food caches, tools, farming (corn, squash, beans and amaranth) and bullboats made from a single buffalo hide.
