It was a short walk across the mesa top between Hovenweep and Negro Canyons. From the west rim of Negro Canyon I could see a green tank and there is a dirt road running along the canyon bottom. Across the canyon on Mockingbird Mesa I could see two of the Carbon Dioxide facilities and the large power lines. I scanned along the far canyon rim with binoculars but didn’t spot any ruins structures.
There was one boulder based collapsed ruins site below the cliffs near the point where I first arrived at the rim and also a circular petroglyph that was visible in the same area. I continued south for about 0.3 miles along the rim and then turned west and found my way back to the original trail. My hike took 5:00 hours for about 5 miles on a relatively cool 65 F mid June day. The biting gnats that swarm in June didn’t appear until the day warmed up later in the afternoon. I carried and drank 3 liters of water.
