Lake Powell used to be Glen Canyon discovered by John Wesley Powell. When the Glen Canyon dam was built, the Colorado River filled Glen Canyon to form Lake Powell. Our cruise day was rainy, but the trip was still beautiful. The interesting marks on the sandstone cliffs were carved out mostly by flash floods. We met kayakers, jet skis, and guys standing on paddleboards. I thought it was interesting that the cliffs all have a lighter-colored lower layer known as “the bathtub ring”. It is a layer of white calcium carbonate that soaked into the sandstone from the highest water mark back in 1983.
