3. Antelope Canyon (USA)
Antelope Canyon is a slot canyon on Navajo (a Native American tribe) land in Arizona. The Navajo name for the canyon is Tsé bighánílíní, which means the place where water runs through the rocks. It was formed by the erosion of sandstone, due to flash flooding. Over time the water smoothed away all the hard edges and the characteristic “flowing” shapes were created.
