Hal, I will try to answer, your question, as I understand it. At first, I had a hypothesis and followed to a viable theory. In 2015 my best friend and my self then flew to Arizona for a week to see if what I thought I had was legit. When I look back now we had very little, and could not get to the site, but got close enough to find a couple of things fit the location. When I look back now we did not have much, except we thought we had the location but really did not know for sure. But I had a few things that were very compelling that we were in the right location. so the following spring we assembled a team and went back. We have been there on several trips with the team since then. WE have learned a lot, and have a team that is very skilled.
To answer your question, we have been able to find many things that fit, but some of the areas are so dangerous it can only be gotten to with repelling gear. This summer the team has been training with professional climbers. On our next trip, two hard-core climbers are going with-us. Hal, we are on the boots on the ground, and would not be going back if we did not have a lot, could we be wrong, anything is possible, but it would be the stranges of stories ever told. So I think to answer yes we had a specific site before we started, and yes, things are matching up. IMO You know when I look back to the first trip in 2015 we were very nieve and really did not have much, so
