Along the Minnesota-Ontario border, in the days of voyageurs, tall trees were used as guideposts in the uncharted wilderness to help fur traders and explorers find their way through the maze of lakes and portages. Branches were cut, leaving the middle of the tree bare with branches above and below. Clifford and Isabel Ahlgren, two of the most knowledgeable ecologists of the area, use nine native trees to serve as lob trees for this book, an ecological history of human activity in the Quetico-Superior wilderness area.

With more than 200,000 visitors annually, the Boundary Waters Canoe Area Wilderness is among the most alluring wilderness areas in the country, unique because it is most often explored by canoe. Comprised of more than one million acres, the BWCAW is an exceptional combination of expansive wilderness, abundant wildlife, and fascinating natural and human history. Exploring the Boundary Waters is the most comprehensive trip planner to the BWCAW, giving travelers an overview of each entry point into the wilderness area as well as detailed descriptions of more than one hundred specific routes—including a ranking of their difficulty level and maps that feature the major waterways, portages, and the designated campsites. The book is crafted so that readers can design their own route through the almost inexhaustible network of lakes and streams. Daniel Pauly, Boundary Waters expert, worked with the U.S. Forest Service, the Minnesota DNR, and local outfitters to collect and present crucial information here: instructions on about how to obtain a permit, the rules and regulations of the park, safety tips, and suggestions about how to help maintain the ecological integrity of the wilderness. As engaging as it is informative, Exploring the Boundary Waters not only contributes advice on the pros and cons of each route, but also brings the reader a natural and historical context for the journey by offering insight into the pictographs, mining sites, logging railroads, and ruins one may encounter on an expedition. With its accessible and personal style, Exploring the Boundary Waters is the perfect guide for anyone—novice or seasoned veteran—arranging a trip to the BWCAW. A companion Web site for this book, http://www.boundarywatersguide.com, presents useful information that can be downloaded for planning a trip, including gear lists, overview maps, and route updates.

Quetico Park in northwestern Ontario celebrates its 100th anniversary in 2009. Long-recognized as a gem among parks, Quetico contains some of the largest stands of old-growth red and white pine in Canada , as well as a diversity of fascinating lichens, carnivorous plants in specialized habitats. The author presents an insightful look into Quetico’s natural history as he examines the adapations that have allowed moose, white-tailed deer, wolves and other mammals to survive. The human history of the park is also explored, beginning with the Objiwa living there when the area was designated as a park, followed by accounts of trappers, loggers, miners, park rangers, and poachers. Beginning with the retreat of the glaciers, the author combines his thorough research into Quetico’s long and varied history with the threads of his own extensive involvement with the park. The result is a splendid tribute to a very special place.

Theodore J. Karamanski's sweeping maritime history demonstrates the far-ranging impact that the tools and infrastructure developed for navigating the Great Lakes had on the national economies, politics, and environment of continental North America. Synthesizing popular as well as original historical scholarship, Karamanski weaves a colorful narrative illustrating how disparate private and government interests transformed these vast and dangerous waters into the largest inland water transportation system in the world. Karamanski explores both the navigational and sailing tools of First Nations peoples and the dismissive and foolhardy attitude of early European maritime sailors. He investigates the role played by commercial boats in the Underground Railroad, as well as how the federal development of crucial navigational resources exacerbated sectionalism in the antebellum United States. Ultimately Mastering the Inland Sea shows the undeniable environmental impact of technologies used by the modern commercial maritime industry. This expansive story illuminates the symbiotic relationship between infrastructure investment in the region's interconnected waterways and North America's lasting economic and political development.
