The wildlife-rich Porcupine drainage on the west slope of the Gallatins, which was supposed to be a prize for wilderness protection following a series of crucial public/private land swaps in the 1990s. It is especially important with Big Sky, located on the other side of U.S. Highway 191, bursting at the seams with human development activity. Photo courtesy
