CommentsWe were exploring the Anasazi arm of Lake Powel via motor boat. We followed the canyon for as long as we could until the opening was too small to be able to turn the boat around. This is where we saw dozens or hundreds of the Madusa phase Freshwater Jellyfish the first time. This is the location where we saw the most Freshwater Jellyfish but unfortunately not the location where I got any pictures. I am submitting another form with the second location and picture.
