Arizona - Upper Antelope Canyon
Page, Arizona: Over thousands of years, wind and water scoured a narrow crevice in the mesa to form a slot canyon in two sections - the Upper Antelope Canyon and the Lower Antelope Canyon. The Upper Antelope Canyon measures a quarter mile long and 130 feet deep. The spectacular landscape dominating this canyon country is the product of eons of geologic activities, shifting continents, global rising and falling of sea levels, and creation of highlands now worn and redeposited. Water invaded, leaving rivers to erode deposited layers and with winds abetting the process, created what is the Antelope Canyon today.
