Arizona was the 48th and last of the contiguous states
admitted to the Union on February 14, 1912, the 50th anniversary of Arizonas recognition as a territory of the United States. Arizona is noted for its desert
climate, exceptionally 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. Population figures for the year
ending July 1, 2006 indicate that Arizona was at that time the fastest growing state in the United States
, exceeding the growth of the previous leader, Nevada
, and is currently the second.
