Based on an evaluation of the four alternatives, the study determined that a Pacific Northwest Trail would have the scenic and recreational qualities needed for designation as a National Scenic Trail, but concluded that its construction was neither feasible nor desirable and recommended the "no trail" alternative. In arriving at this recommendation, the study found that little new recreation opportunity would be provided if a trail were constructed since extensive trail systems already exist throughout most of the study area; that the cost of land acquisition and construction would be excessive (from $64 million to $106 million based on a width averaging 1,000 feet and from $39 million to $60 million for a width averaging 500 feet) in comparison with the benefits which would result; and that there would be significant adverse environmental impacts on the grizzly bear and on fragile and frequently over-utilized high elevation areas.
