It is of interest as there are Ancestral Pueblo ruins tower structures known as the McLean Basin Towers. The first challenge is to find a route to hike down into the canyon basin, and the second is to find the towers.
Canyons of the Ancients is a find it on your own National Monument and there are very few official trails and limited information on where the interesting sites to hike to are located. I started my exploring at Pedro Point, where there is a good but unpublicized ruins site. This site is along the hike I call the McLean Basin South Rim Trail.
Scanning with binoculars from the canyon rim I couldn't pick out any of the elusive towers. There isn't a trail descending into McLean Basin here, but there is a drainage flowing away from the Pedro Point site that can be followed and allows a route through a steep sandstone cliff that is part of the way down the slope. The route isn't easy but is feasible.
On the flat area just below the steep cliffs, I noticed a small ruins site a little to the east of the drainage. This is still only about half the way down into the basin. This site is mostly circular and has some dry wall sections still standing, with the rest as rubble piles .
It seemed to be isolated, I didn't notice any other structures in the vicinity. There might be a grain grinding spot nearby. From here, the hiking is probably easier away from the small drainage. The slope is walkable and there are cow trails to follow down to the bottoms area where there is a flowing stream.
I crossed the small stream and made my way past a small group of cows to a road on the north side of the basin. In the center of the basin below Pedro Point there is a large hill. The road appears to be easily driveable for those who want to drive to this remote area. Scanning ahead, a rocky elevated point appeared to have some sort of organized rock pile on the top.
Climbing up to the top of this rocky point, this site looks like it could have been a large circular kiva and tower combination. It is positioned with a good view over the sage brush basin floor and the winding stream. Sage brush is supposed to indicate good soil for farming and the stream is a source of water.
I spent 4:30 hours on this hike but only covered about three miles. Most of the hike is picking a route up and down rocky slopes and I spent a lot of time scanning and viewing the sites. I didn't find the elusive McLean Basin towers this time.
