Antelope Canyon was formed by erosion of Navajo Sandstone, which belongs to the Indian Reserve. It includes two separate, Upper and Lower Antelope Canyon. When the sunlight shines through the mountain side craves and causes a reflection on the rock, you will see so many bright vivid colors. You feels like you are walking in the dream. The colors are so beautiful that makes you feel this can not be real. A must see, though this place doesn't count as a National Park. However, as an artist, I have an extreme passion to paint this place.
