Tom,
You may be right about this as I don't think that the shape is right for the office. I need to try and line the photos up with my GPS track and compare to the maps. I should have layed down waypoints for each of the structures to precisely note the location. I guess that I was too busy exploring and having fun! I'd certainly like to get back up there and explore some more. Next time I'll have a better idea of what I want to concentrate on. As you can see from my plot I didn't make it around the other loop up on top.
