Antelope Canyon is one of my favorite places to photograph.
Upper Antelope Canyon is called Tsé bighánílíní, ‘the place where water runs through rocks’ by the Navajo. It is the most frequently visited by tourists for two reasons. First, its entrance and entire length are at ground level, requiring no climbing. Second, beams or shafts of direct sunlight radiating down from openings at the top of the canyon are much more common in Upper than in Lower. Beams occur most often in the summer months, as they require the sun to be high in the sky. Winter colors are more muted. Summer months provide two types of lighting. Light beams start to peek into the canyon on March 20 and disappear on October 7 each year.
