Rocky Mountains, byname the Rockies, mountain range forming the cordilleran backbone of the great upland system that dominates the western North American continent. Glaciation of the southern hemisphere raised and lowered sea levels in Arizona, creating the ledge and slope topography common in the Grand Canyon, Sedona and Monument Valley, with alternating layers of siltstone, limestone, sandstone, dolomite and shale. The Mescal Limestone metamorphosed, forming asbestos and superheated diabase magma "baked" the limestone to marble. [3]. In urban areas, groundwater is now mainly recharged from excess irrigation, urban surface runoff, canal seepage and years of higher than average rainfall. As mentioned earlier, recent glaciations include the Bull Lake Glaciation, which happened between 300,000 and 127,000 years ago, and the Pinedale Glaciation Period, which took place from 30,000 to 12,000 years ago.

There have been two significant periods of glaciation over the last 300,000 years. Shortly afterward, a large volume of magma pushed into the older rock around 1.6 billion years ago, resulting in the Boulder Creek Batholith, which is why youll find lots of metamorphic rocks within the Rockies that may have been caused by regional metamorphism. The first period of activity preceded the delineation of the Colorado Plateau and Basin and Range geologic provinces, and is contemporaneous with volcanism in the Mogollon Plateau region of New Mexico. The Tucson Mountains are largely the remains of an immense, more than 15-mile-long volcanic caldera, or collapsed volcano. If you go down to the San Tan Mountains, Skotnicki said, you can still see several hundred feet thick of those deposits, 40 miles from the Superstitions., Gootee said a supervolcano essentially is a shotgun that just blows a hole in the crust. 70 Million Years Ago It has been proposed that The Tucson Mountains were actually the top of a giant volcano.

As the mountains were uplifted, it is likely that the Santa Margarita River was able to wear away the rock as fast as it was uplifted, staying in the same place at the same height as the rocks rose around it. The Coast Ranges formed as large slabs of crust were accreted, or stuck, onto the North American plate. 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 mountain ranges took shape during an intense period of plate tectonic activity, leading to a more rugged landscape in western North America. Copy.
