Man.... you must of been reading my mind... I wanted to do the same thing, and in fact had hoped to do it this year until Colorado kidnapped me so I ended up not doing the Subway. I wanted to get up into that next section, it didn't seem that it would be that difficult but last year we just were running too late to try it.
You have some really cool images here. The one I like the least, is #3 looking back down into the normal subway. You might have just meant it as a reference shot, but if you tone down the highlights in the foreground rock, I think it could be pretty cool. #4 and 5 are my favorites!
