In the Frank Church Wilderness, the only means of transport and accessing supplies are by way of the largest un-dammed river in North America, the Salmon River, commonly referred to as âThe River of No Return.â Under these circumstances, the residents of âThe Frankâ tackle everyday life in one of Americaâs last frontiers â from twenty-somethings seeking to test their limits, to the living legends of the River who have chosen to spend their lives there.
