The only access for hikers in this area is the Sand Canyon Trail. There are horse trails that lead to the area east of the main Sand Canyon Trail but for a hiker it is a fairly long trek.
Follow the drill hole road past the Mad Dog Tower site a few hundred yards to a vague two track trail. Then continue east to the small pipe lines that shoot up to the top of the mesa. There is another horse trail a few hundred yards south along the pipelines that crosses the pipelines and leads another mile or so to this site.
On a previous hike it took me 2:30 hours to get to Mad Dog Tower using the main trails and it is another 0:30 minutes to get to this eastern site. The 3:00 hours assumes that there is no stopping at the 20 or more ruins sites along the way.
There is a good alcove site in the eastern side canyon with a lookout point ruin above the alcove. The upper end of the east side canyon is near the drill hole road and a few hundred yards south of the Mad Dog Tower. From the drill hole road, find the horse trails and continue east.
A few hundred yards south and east of Mad Dog Tower there is another circular structure that has a dead Juniper tree in the middle of it. I missed this site when I was hiking east from Mad Dog Tower on the previous hike. It is close to the horse trail but not very near the rock face where I was looking at the alcoves.
I followed the Mouth of Sand Canyon route both out and back and stopped at the mouth alcove ruins and the lookout ruin above it. With another short stop at the circular neighbor of Mad Dog Tower, it took me 3:00 hours to arrive at this site. My return hike without stops took 2:00 hours and my total hike was 5:15 hours for about 6.5 miles on a 55 F blue sky day in late November. I carried and drank two liters of water.
