The state is a large geographical area (147,046 square miles (380,850 km2)) that is split by the Continental Divide, resulting in watersheds draining into the Pacific Ocean, Gulf of Mexico and Hudson's Bay. The state is approximately 545 miles (877 km) east to west along the Canadian border and 320 miles (510 km) north to south. The fourth largest state in land area, it has been divided up in official and unofficial ways into a variety of regions. Additionally, Montana is part of a number of larger federal government administrative regions.

Climate regions[edit]

In the Köppen climate classification system, Montana is predominantly a BSk (Semi-arid or Steppe) climate, with the Mountainous areas, mostly in the western parts of the state, listed as Dfb (Humid continental). Areas near Granite Peak and the highest elevations in Glacier National Park are Dfc (Continental subarctic), and a small area in the northwestern corner of the state near the Idaho border listed as Dsb (Warm summer continental).[32] The United States Department of Agriculture places most of Montana in Plant Hardiness Zones 3 and 4, with limited areas in zone 5 with a small sliver of the state centered in Sanders County in zone 6. These zone boundaries correspond closely to the Köppen classifications.[33] For purposes of the 2009 International Energy Conservation Code, which provides minimum insulation standards for home construction based on climate, the entire state is classified in climate zone 6, reauiring higher levels of insulation than are recommended in more temperate climates.[34]
