Mesa Verde National Park offers adventure through nature and a history lesson all in one. The 52,000 acre park was first designated in 1906 to protect more than 5,000 known archaeological sites. The park is best known for its preserved cliff dwellings, archaeological proof that the Ancestral Puebloan people made the cliffs their homes as far back as 600 BC. Today, half a million people visit the park each year to learn about the archaeological sites and to literally look through the windows of time itself. Anderson Design Group honored the park in its own, early-1900s travel art illustration of one of the many cliff dwellings found within Mesa Verde's protected borders.
