I join friends for a boat ride upriver. I fill my entire camera card with photos. It was like a mini-Grand Canyon raft trip, similar spectacular scenery but louder and without all the sand in your food. Ospreys and herons every quarter-mile. However it is well-beloved of fishermen and duck hunters; unlike the Grand Canyon solitude is unlikely. And it was bizarre to round the last corner and see the dam. Also strange to see the Colorado so clear and green: because it’s coming out of the bottom of Lake Powell it lacks the silt and sediment of its enormous watershed. I am reading Tim Egan’s Lasso the Wind; he reminds me of the great irony of the lake behind it named for John Wesley Powell, who argued for climate-appropriate development in the arid southwest and failed.
