Yes, it's very strange boating in a hard desert. Amazing rock formations and twisting canyons. Suspect it gets very busy in Season with pontoon boats to the fore.
It's somewhere I'd like to go back to and to spend a week on the water.
charted a small boat here a few years ago and an amazing experience. unique scenery. not much good long term as there is nowhere much to go - just cruise around with lower jaw pemanently slack
