Well, one can hope the third time is the charm. In the case, it ALMOST was.
I took time away from this yeast bread business to "back up and regroup". It must have been the right thing to do because my third attempt at high altitude yeast bread actually had much much better results.
I kept the same recipe as the last time (yes, the vortex recipe). I even made the 2 lb. loaf though I had considered making the 1 lb. loaf instead. I only increased the flour by a smidgen (2 tsp.). I also kept a close eye on it that last hour of rise time, going so far as to open the lid and poke the dough to keep it from rising over the sides of the pan again. This kept the air flowing throughout the bread machine.
This recipe tasted great, looked worlds better than the last couple of attempts and was gobbled up. I'd say it's a success, except I don't want to have to babysit the bread every time I make it. Next time it's a 1 pound loaf and I'll let it rise to it's heart's content! :)
