Carved into the reds and golds of northern Arizona sandstone, Antelope Canyon is among the world’s most photogenic natural landscapes. Formed by water rushing through rock, it’s a slot canyon – a narrow gash in the earth – its swirling ridged rock walls a canvas of extraordinary colors in subtle grades from muted purple to bright orange. When the sun is at its highest point, beams of light shoot down from above so brightly and powerfully they look tangible.
