Apologies if this excellent photograph has been posted on here previously. I don't have a credit for it. It appears to show a swollen Colorado river meeting the flat water of a rapidly-rising Lake Powell at the mouth of White Canyon. If that is the case, this picture would have been taken on, or about, June 10th 1964. The reservoir was rising by approximately two feet each day at that time and looking at the condition of the river you can see why. Judging by the tree line, the elevation of the reservoir was ~3450 at that moment. The Hite ferry landings would have already been under several feet of water. Of course, center right is the magnificent Moki fort which would eventually have 150 feet of water above it. That's quite hard to get your head around when looking at this picture!
