The U.S. state with the northernmost point is Alaska.

Alaska's northernmost point is located at Point Barrow (Nuiqsut), positioned just above the Arctic Circle. This makes Alaska the state with the furthest northern reach in the U.S. Known for its extreme Arctic climate, the area experiences long, harsh winters and short, cool summers. Point Barrow is an important location for scientific research, particularly in studies related to climate change, as it is a key area for observing the effects of warming in the Arctic. The state’s unique geography and wildlife, such as polar bears, draw researchers and adventurers alike.
