Today we toured the lower Antelope Canyon at 830 this morning. The lower canyon required stairs to get down into it. It was narrow at the bottom. Both were similar. The upper canyon had more light, but it could be because it was after noon. The upper canyon required a dirt road trip 3 miles into the Navajo Reservation in a truck designed to take tourists to the cave/canyon. During the monsoon season these canyons can flood within 15 minutes with water rushing through at 50-60 miles per hour. They are definitely a safety hazard if there is rain nearby. The upper Antelope Canyon has the million dollar wall called the WAVE seen on Microsoft computers. The tour guide helped me recreate that picture as well.
