From the Gros Ventre Valley of Wyoming to a Walmart parking lot in Logan, Utah, environmental journalist Ben Goldfarb traveled to all kinds places for his new book, Eager: The Surprising, Secret Life of Beavers and Why They Matter. Goldfarb says beavers have super powers. In fact, he calls them ecological and hydrological swiss army knives. And in the right circumstances, Goldfarb says they can tackle all kinds of problems that plague the West. Wyoming Public Radio’s Maggie Mullen spoke with the author ahead of his visit to Teton County Library Wednesday, September 26 starting at 5 p.m.
