Often viewed in isolation, the Jolliet and Marquette expedition in fact took place against a sprawling backdrop that encompassed everything from ancient Native American cities to French colonial machinations. Mark Walczynski draws on a wealth of original research to place the explorers and their journey within seventeenth-century North America. His account takes readers among the region's diverse Native American peoples and into a vanished natural world of treacherous waterways and native flora and fauna. Walczynski also charts the little-known exploits of the French-Canadian officials, explorers, traders, soldiers, and missionaries who created the political and religious environment that formed Jolliet and Marquette and shaped European colonization of the heartland. A multifaceted voyage into the past, Jolliet and Marquette expands and updates the oft-told story of a pivotal event in American history.
