From grizzly bears in northern Alaska to jaguars in Mexico, the reach of the Rocky Mountains is comprised of unique and diverse wildlife and wildlands. Author Mary Ellen Hannibal calls that 5,000-mile stretch the "spine of the continent." Her new book documents a historic and ambitious project to save the region's wildlife by creating linked protected areas from the Yukon to Mexico. She joins us to talk about the book, and the unique people who are determined to preserve the Rockies and beyond.
