The Driftless Area is the land the glaciers missed, an ancient landscape of bluffs, ridgetops, and steep valleys that long ago was a seabed. Covering much of southwestern Wisconsin, its contours were deeply carved from bedrock, not by ice but by many rivers.

Crossing the Driftless is both a traveler's tale and an exploration of this dramatic environment, following the streams of geologic and human history. Lynne Diebel and her husband, Bob, crossed the Driftless Area by canoe, journeying 359 river miles (and six Mississippi River locks and five portages) from Faribault, Minnesota, where her family has a summer home on Cedar Lake, to their Wisconsin home in Stoughton, one block from the Yahara River. Traveling by river and portage, they paddled downstream on the Cannon and Mississippi rivers and upstream on the Wisconsin River, in the tradition of voyageurs. Lynne tells the story of their trip, but also the stories of the rivers they canoed and the many tributaries whose confluences they passed.
