At close to 2.4 million acres, the Frank Church-River of No Return Wilderness is protected under the Central Idaho Wilderness Act that was passed by U.S. Congress in 1980. This area of Idaho wilderness is where Isaac and Bjornen Babcock spent their year-long honeymoon in the PBS Nature film, River of No Return. A map of The Frank Church-River of No Return Wilderness:
