The rich and diverse natural resources of Denali National Park in Alaska are managed by the US National Park System as regulated by Park laws and the Alaska National Interest Lands Conservation Act. This Act prohibits snow machine use within a designated wilderness area, a law which has been challenged by recreationalists. This examination of the legal discretion of the Park authorities to enforce this law focuses on snow machine policy, scientific evidence of impacts to the natural environment, management objectives for this Park, National park Service authorization for regulating visitor uses of the park, and agency decision making in general.
