The Mid-Tertiary ignimbrite flare-up created smaller mountain ranges with extensive ash and lava in the Cenozoic, followed by the sinking of the Farallon slab in the mantle throughout the past 14million years, which has created the Basin and Range Province. In this torn fabric, from Montana to Mexico, great blocks of crustal rock started to settle downward and form vast valleys -- the Valley of the Sun is one. Due to uplift during the Taconic orogeny, the sea retreated and Arizona returned to continental conditions during the Ordovician and Silurian leaving few rocks from these time periods.

The mountains were actually formed when a large caldera volcano erupted and basically churned up the rock. Between 1915 and 1983, an estimated 81million acre feet of groundwater was pumped in the vicinity of Phoenix, to complement surface water from the Salt River, Verde River and Agua Fria River. The Grand Canyon is being eroded deeper at a rate of 1 foot every 200 years. As the mountains have a desert climate and few water resources, there is not much vegetation here.
