How big is North Slope in Square miles?

Answer 1

The borough has a total area of 94,763 square miles (245,436 km²), of which, 88,817 square miles (230,035 km²) of it is land and 5,946 square miles (15,399 km²) of it (6.27%) is water. Its western coastline is along the Chukchi Sea, while its eastern shores (beyond Point Barrow) are on the Beaufort Sea. The North Slope Borough is the largest county-level political subdivision in the United States by area, with a larger land area than that of the state of Utah. Although the adjacent Yukon-Koyukuk Census Area is larger in area, it has no borough-level government. The borough is also the third-least densely populated county-level entity in the United States (after the Yukon-Koyukuk Census Area and the Lake and Peninsula Borough).
