Ken Sleight was an old river runner/desert rat who was the inspiration for Ed Abbey’s character “Seldom Seen Smith” in The Monkey Wrench Gang.”

I like that he calls Lake Powell “Lake Foul.”

“It was probably foolish and masochistic of me to have hung around and watched it happen. But I just had to. At first it would rise a foot overnight, and you saw things you loved go under. First it was Music Temple. Then it was Gregory Natural Bridge. Then Cathedral in the Desert. I’d think of those fools that said this was a good thing, that we needed this dam. Then I’d see Hidden Passage or some other lovely spot with no name go under…it was unbearable.

“And I’ll always remember the sign at Rainbow Bridge. There was a Park Service sign along the trail and it read: ‘God’s Work. Tread Lightly.’ The next week, the lake came up and buried the sign and the trail.” By late 1964, the reservoir had reached Hite and Glen Canyon was gone…for now.”
