Earth's Shadow - Powell Point

Jumping ahead a number of hours, Jim and I shot the second sunset of our trip to the Canyon at Powell Point, west of Grand Canyon Village. After the sun set, we were getting redy to pack thiings up and head back to the hotel when Jim suggested we stay a while and see how the colors developed.
We had noticed the night before that the Earth's shadow was visible in the sky *before* the Sun had set. Usually a very uncommon event.
Jim made the correct call, for as the twilight drew us deeper into night, the Earth's shadow rose higher in the sky and the rocks of the canyon walls became more saturated in the fading light.
