On 8/21 I took a trail to a pinnacle between two canyons and glassed the canyon walls looking for ruins. In the East canyon on the East wall I found four ruins, two of which are worth visiting.
This is the best of two.

This is the second best.

Today, 8/22, I climbed a steep boulder strewn canyon bottom to climb to the ruins. Given the time I had I was only able to reach the least of the two ruins. Here's a photo of it close up.

In the back corner you can see signs of a camp fire smoke on the wall. Two smaller ruins appear to be food storage ruins but I didn't climb to them or take photo's.
Tomorrow I will go to the pinnacle and glass the wall again to find the best way to get to the better ruin. I may be able to descend the canyon wall rather than climb up.
