Arizona actually is quite varied in it's topography as can be seen on this physical map. My home is in the south east corner, between the mountain ranges. Phoenix is the capital and it is the most populous state capital in the US. It's located close to the dead center of the state. It is much hotter in Phoenix than where I live. Most of the lakes in Arizona are man-made, including all you can see on this map. Water is everything in an arid climate like this. Arizona is surrounded by Mexico, New Mexico, Colorado, Utah, Nevada, and California. The 200 mile long Grand Canyon was formed by the Colorado River cutting jaggedly across the northwest corner of the state. The wide-spread use of central air-conditioning in this sunny clime has made the state attractive to new residents and it is now the fastest growing state in the USA.
