8. Antelope Canyon, Monument Valley
This Arizona attraction can be found just east of Page, Arizona and is situated on Native American Navajo land. The canyon actually consists of two adjacent slot canyons; water formed these by carving narrow, deep passageways as it ran through several kinds of rock, most predominantly sandstone, limestone, granite and basalt. It was named after the pronghorn antelope, which used to live in the canyon, in addition to the cattle that once grazed in it. And even though Antelope Canyon is hugely popular with photographers, visitor tours only began exploring it as recently as 1997. This is when the Navajo people made the area into a Navajo Tribal Park.
