Mudfossil Hunt in Arizona, Day 5. Another Unexpected Great Mudfossil Find. Petrified stumps?

One of my friends had located in his spotting scope a cave hidden in a cliff face in a remote area so we headed out to find it. What we thought would be a fairly simple and quick hike turned out to be just a bit more than we expected. Along the way, we noticed that we were walking through sections of petrified or fossilized tree stumps, ranging in diameters from roughly 3' to about 12'.. We walked through some areas conspicuously littered with large numbers of round stone balls, ranging in diameters from roughly 8" to about 5'. The largest of the round stone balls we found are around the 13 minute mark of the video and the smaller ones are before that. All I could see was an ancient forest of junipers or cedars, some with, by today's standards, absolutely enormous trunks. To me, the round stone balls looked like fossilized juniper berries. The friend who was with me saw it as one gigantic tree, just like the one we had discovered on Day 3, and that the "stumps" we were looking at were simply branches. After reviewing the video to edit it, I lean in the direction of my friend's theory that it was, indeed, one gigantic tree, over which we hiked. We first stumbled into the petrified "stumps" about 1/2-mile into our hike and those "stumps" continued for about another mile. There was a brief section after that, during which we got out of the petrified wood. But as we got closer to where we had to descend to the cave, we climbed down into what appeared very strongly to be another gigantic tree lying almost parallel to the one above, pointed in the opposite direction (back in the direction from which we had come), underneath the one over which we had walked hiking in. It is difficult to explain without a drawing, but based on what we saw, it appeared to be two gigantic trees that were roughly 2 to 2-1/2 miles apart at the bases and they either fell or were felled directly at each other, the tops of each overlapping the other a little. As difficult as it is to type this, based on what we observed, the trees would have been over a mile tall. I can't explain it. I'm only stating what we observed. Such thoughts stagger the mind, but based on at least our initial observations, that appears to be what we were hiking over. The two caves we found would have been cavities in the tree that was on the bottom.
