The state of Arizona is located in the western United States as one of the Four Corners states. Arizona is well known for its desert climate, very  hot summers, and mild winters, but the high country in the north features pine forests and mountain ranges with cooler weather than the lower deserts. It is the largest landlocked US State by population. Arizona is home to one of the most well-preserved meteorite impact sites in the world. And best of all Arizona is the fastest growing state right now.
