Ohio offers a blend of surprises that range from ancient earthworks to world-class roller coasters. In the southern part of the state, the newly designated Hopewell Ceremonial Earthworks tells the story of a sophisticated Native American culture that built massive geometric mounds over 2,000 years ago. Visitors can walk among these quiet, grassy structures and learn how they were used for ceremonies, astronomy, and social gatherings long before European contact.

Lake Powell, stretching across the Utah-Arizona border, is one of the largest manmade reservoirs in the United States. Formed by the flooding of Glen Canyon after the completion of the Glen Canyon Dam in 1963, it covers over 180 miles in length and contains nearly 2,000 miles of shoreline, more than the entire West Coast of the U.S. Despite its modern origins, the area has long been home to the Ancestral Puebloans and later Navajo communities.

Tikal is one of the most extraordinary ancient cities in Guatemala, hidden deep in the Petén region’s tropical forests.

Today, visitors can walk among the Great Plaza and gaze up at the Temple of the Great Jaguar and the Temple of the Masks, reminders of the city’s long legacy.
