Coastal cliffs between Cook Inlet and the eastern side of Lake Clark National Park hold fossil remnants of 150 million years of sea life.

Please look at, touch, and enjoy these unique fossils! We ask you, however, to resist the temptation to take them home. Removing fossils from the park and preserve is illegal. Although Lake Clark seems remote, in fact many people visit the area. If visitors take fossils and other artifacts, eventually there will be no more left and our national heritage will be impoverished.
