In 1912, Arizona became the final of the 48 contiguous states to be admitted to the Union. It is known for its desert landscape and is home to one of the most famous natural wonders of the world, the Grand Canyon. The Colorado River took millions of years to carve the breathtaking 277 mile long canyon, which reaches depths of more than a mile. It may have taken eons to create the landscape, but it only took about 50 years following World War II for the population of Arizona to more than quadruple. The Arizona population boom continues today - between 2005 and 2006, Arizona was the fastest growing state in the country. The draw of the Southwest lifestyle is undeniable, and the Arizona luxury home market is stocked with enough wonderment to fill the largest of canyons.
