On the return east along the rim toward the first mesa top site I spotted another site that is about 200 yards to the west of the first site. I only looked at this site from the rim. It isn’t very visible from below.
It took me 2:00 hours to reach the first ruins site, but I spent much of that time looking and scanning and deciding which way to go. I spent 1:00 hour viewing the sites and the return hike took 1:00 hour for a total of 4:00 hours for about 4 miles of hiking. I carried and drank two liters of water on a 60 F degree late April day.
