We began at Owl around 2pm in 95°F weather. We came upon our first ruin, about half a granary, about 100 feet from the top. The second bunch of ruins we almost missed, being hidden behind a "waterfall". We didn't see any after those until we reached the confluence, at which we decided to take a day hike south. We came upon 2 granaries on that hike, one circular and one rectangular structure. There was another granary we found that was falling apart. All of the structures going past the confluence were very hard to spot and very easy to miss with their camouflage construction.The easiest way to spot them is to look for their perfect square openings. We didn't see any structures on our way back up Fish. Although there is a small creek with flowing water right along the trail. I'd do this hike again and make my way farther south to find more structures if I knew there was water to be found south of the confluence.
