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 ex-
traordinary 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 mem-
bers from public and private entities completed a 
study endorsing the establishment of an Ice Age 
Floods National Geologic Trail to recognize the na-
tional significance of this phenomenon and to coordi-
nate public and private sector entities in the presen-
tation of the story of the Ice Age Floods. 
(b) PURPOSE.—The purpose of this Act is to des-
ignate the Ice Age Floods National Geologic Trail in the 
States of Montana, Idaho, Washington, and Oregon, ena-
bling the public to view, experience, and learn about the 
Ice Age Floods’ features and story through the collabo-
rative efforts of public and private entities.

(3) FLOODS.—The term ‘‘Ice Age Floods’’ or

SEC. 4. ICE AGE FLOODS NATIONAL GEOLOGIC TRAIL. 
(a) DESIGNATION.—In order to provide for public ap-
preciation, understanding, and enjoyment of the nationally 
significant natural and cultural features of the Ice Age
