3	Bogoslof Island		1967	Aleutian Islands	Aleutians West	The island is part of the Alaska Maritime National Wildlife Refuge . It was created from several volcanic eruptions. During the last eruption in 1992, a rock dome was formed in the east of the island. Bogoslof Island is a nesting place for over 50,000 sea birds and a refuge for the endangered Steller sea lions .
4th	Clarence Rhode National Wildlife Range		1968	Yukon-Kuskokwim Delta	Bethel	The Wildlife Range is a coastal and highland biotope with thousands of lakes, meandering rivers and tidal flats within the Yukon Delta National Wildlife Refuge .
5	Mount Iliamna		1976	Chigmit Mountains	Kenai Peninsula	Mount Iliamna is a stratovolcano in Lake Clark National Park . Most of the mountain is covered in snow and ice. At least ten glaciers lie on its flanks.
6th	Lake George		1967	Chugach Mountains	Anchorage	At the time it was designated a National Natural Landmark, Lake George was the largest lake in North America dammed by a glacier. The Knik Glacier blocked the outflow in winter and caused the water level to rise, in summer the barrier broke and the lake water poured into the Knik River in a large tidal wave .
