SECTION 1. SHORT TITLE.

Trail Designation Act''.

SEC. 2. FINDINGS AND PURPOSE.

    (a) Findings.--Congress finds that--
            (1) at the end of the last Ice Age, some 12,000 to 17,000 
        years ago, a series of cataclysmic floods occurred in what is 
        now the northwest region of the United States, leaving a 
        lasting mark of dramatic and distinguishing features on the 
        landscape of parts of the States of Montana, Idaho, Washington 
        and Oregon;
            (2) geological features that have exceptional value and 
        quality to illustrate and interpret this extraordinary natural 
        phenomenon are present on Federal, State, tribal, county, 
        municipal, and private land in the region; and
            (3) in 2001, a joint study team headed by the National Park 
        Service that included about 70 members from public and private 
        entities completed a study endorsing the establishment of an 
        Ice Age Floods National Geologic Trail--
                    (A) to recognize the national significance of this 
                phenomenon; and
                    (B) to coordinate public and private sector 
                entities in the presentation of the story of the Ice 
                Age floods.
    (b) Purpose.--The purpose of this Act is to designate the Ice Age 
Floods National Geologic Trail in the States of Montana, Idaho, 
Washington, and Oregon, enabling the public to view, experience, and 
learn about the features and story of the Ice Age floods through the 
collaborative efforts of public and private entities.
