SECTION 1. SHORT TITLE.

     This Act may be cited as the ``Ice Age Floods National Geologic 
Trail Designation Act of 2004''.

SEC. 2. FINDINGS AND PURPOSE.

    (a) Findings.--Congress finds the following:
            (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 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 many Federal, State, tribal, county, 
        municipal, and non-governmental lands in the region.
            (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 to recognize the 
        national significance of this phenomenon and 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 Ice Age Floods' features and story through the 
collaborative efforts of public and private entities.

SEC. 3. DEFINITIONS.

     As used in this Act:
            (1) Trail.--The term ``Trail'' means the Ice Age Floods

committee--
            (1) shall include representation from the local, State, 
        tribal, and Federal governments with interests in the floods 
        and representation from the Ice Age Floods Institute; and

governments, private citizens, and interested nonprofit organizations, 
including the Ice Age Floods Institute. The trail advisory committee 
shall assist the Trail manager and staff with the operation of the 
Trail.
    (e) Management Plan.--Not later than 3 years after funds are made 
available for this purpose, the Secretary shall prepare a Cooperative 
Management and Interpretation Plan for the Trail in consultation with 
State, local, and tribal governments, the Ice Age Floods Institute,

Management and Interpretation Plan shall--
            (1) describe strategies for the coordinated development of 
        the Trail, including an interpretive plan for facilities, 
        waysides, roadside pullouts, exhibits, media, and programs that

        study entitled ``Ice Age Floods, Study of Alternatives and 
        Environmental Assessment'' (February, 2001) by locating 
        features more accurately, improving the description of 
        features, and reevaluating the features in terms of their 
        interpretive potential; and

donation or exchange and only after consultation with the affected 
local governments.
    (g) Interpretive Facilities.--The Secretary may plan, design, and 
construct interpretive facilities for sites associated with the Trail 
if the facilities are constructed in partnership with State, local, 
tribal, or non-profit entities and are consistent with the Cooperative 
Management and Interpretation Plan.
    (h) Private Property Rights.--Nothing in this Act shall be 
construed to require any private property owner to allow public access
