JD Marshall Shipwreck
Just off the shoreline of Indiana Dunes State Park rests the JD Marshall, a wooden, steam-powered lumber boat that sank in 1911 while transporting lumber and sand between Indiana and the Chicago area. Located roughly 300 yards from shore, the wreck became Indiana’s first underwater nature preserve in 2013. Marked by historic buoys and an anchoring boat, the site is accessible to divers who want to explore an evocative piece of Great Lakes maritime history and learn how commerce and industry shaped the region.

Angel Mounds State Historical Park
Angel Mounds preserves one of the best-kept examples of the Mississippian Tradition in North America. Occupied between approximately 1000 and 1450 A.D., the site contains earthwork mounds, plaza areas and remnants of a thriving pre-contact community. Archaeologists and visitors alike can explore exhibits and trails that tell the story of a sophisticated culture—its social structure, trade networks and daily life—providing a rare window into Native American history before European contact.
Marengo Cave
Discovered in 1883, Marengo Cave is one of Indiana’s most popular natural attractions and a designated National Natural Landmark. The cave features spectacular formations and well-maintained visitor routes, including the Crystal Palace and Dripstone Trail. Guided tours introduce guests to the cave’s geology and history, while additional activities such as gemstone searches, camping and an interactive cave simulator make it an engaging destination for families and adventure seekers.

Indianapolis Catacombs
Located beneath Indianapolis’s City Market, the so-called Catacombs are a network of arched passageways and columns that reveal layers of the city’s past. Once part of Tomlinson Hall—destroyed by fire in 1958—the underground space has served many purposes over time, from storage and emergency shelter to elegant dining and public events. A failed 1970s renovation attempt to convert the area into an underground shopping mall gave the site its nickname. Today the Catacombs are an atmospheric reminder of urban history and a unique venue for tours and special events.

Mounds State Park
Mounds State Park preserves a landscape shaped by ancient peoples who constructed earthen mounds used for ceremonial and possibly astronomical purposes. Construction of the signature mounds began around 250 B.C. and continued for centuries, with evidence suggesting the site played a role in burial rites and religious observances. Today the park offers trails, interpretive signs and scenic overlooks that help visitors connect with the region’s prehistoric past and understand the cultural importance of these enduring earthworks.
Whether you’re drawn by underwater wrecks, earthwork mounds or underground passageways, these Indiana sites offer compelling stories and opportunities for exploration. Each location provides a different perspective on the state’s natural and cultural history—ideal for travelers who want to follow in the spirit of adventure that defines Indiana Jones, while staying grounded in real history and preservation.
