* Karsten Heuer walks with North American mammals from Yellowstone to the Yukon (Y2Y) to document the animals that use this natural corridor and learn its importance* Preserving the Y2Y corridor has become one of the most critical environmental issues of our day* Winner of the Banff Book Award for Mountain Literature* Grants will fund a multi-city author tour for lectures and presentations related to the Y2Y initiativeWalking the Big Wild is the story of Karsten Heuer's extraordinary 18-month journey of hiking, sking, and paddling across 2100 miles of mountains, forests, and rivers from Yellowstone National Park in Wyoming to the Canadian Yukon. Accompanied by occasional human companions and a remarkable border collie named Webster, Heuer encountered immense challenges: storms, avalanches, floods, and grizzlies. At the end of the journey, Heuer proved that there is nearly continuous wilderness that can support wildlife along the length of the Rockies-and is salvageable if the right decisions are made now.
