Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory separate Alaska from Washington state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent.

The Alaska Conservation Society was the first grassroots environmental conservation group in the U.S. state of Alaska. It was founded in 1960 to coordinate opposition to Project Chariot, a plan to blast a harbor at Point Hope, Alaska, using nuclear explosions. The group subscribed to environmental preservation and the principles of conservation. After the defeat of Project Chariot, the group decided to fight the proposed Rampart Dam project on the Yukon River. After succeeding, the society took a stance on the development of the Trans-Alaska Pipeline System, encouraging environmental mitigation during and after its construction. This led to the society becoming a major factor in environmental policy within the state. The group operated between 1960 and 1993 and was superseded by the Alaska Conservation Foundation, which was founded in 1980 and still operates today.
The Koyukuk National Wildlife Refuge is a 3,500,000-acre (14,000 km2) conservation area in Alaska.

This region of wetlands is home to fish, waterfowl, beaver and Alaskan moose, and wooded lowlands where two species of fox, bears, wolf packs, Canadian lynx and marten prowl.
