The road continues out to a point with good views toward the canyon junctions to the west. On the return hike I tried to follow cow trails back to the east that were closer to the south facing rim and pass through a different section of mesa top. It seems like there should be more ruins sites in this area, but I didn’t spot any.
I did see some isolated pottery shards, one with some black on white design. I was able to spot the boulder top lookout point ruins site across the canyon that I had visited on a previous Burro Canyon south rim hike, but didn’t see any others this time. The boulder top site stood out even though it was about 0.5 miles away. My total hike took 3:30 hours for about 7 miles on a 50 F degree early May day. I carried and drank 2 liters of water. (There are more ruins sites in this area. I just didn't find them on this hike.)
