which state is the biggest
Alaska has a longer coastline than all the other U.S. states combined. It is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separates Alaska from Washington. Alaska is thus an exclave of the United States, possibly the largest exclave in the world. It is technically part of the continental U.S. , but is often not included in colloquial use; Alaska is not part of the contiguous U.S., often called the Lower 48 .
