There's a small tent city in there. Somewhere. It's a big place. Also, while you could probably make it this far without any headlamp at night (or, say 5 am), you'd be in serious trouble from this point on without a headlamp or the sun. Possibly a bright full moon, but it would be very tricky. And dangerous. With all the big stone steps on this trail, starting with a headlamp from the parking lot would probably be a wise decision (I make a note of that for next summer).
So, at this point I've gotten to tent city (sorry, no photos, don't think my mind was thinking too much about photos at this time). And I've begun to more fully appreciate problem number 2. I'm having serious issues with my lower body..."no, foot, I did NOT tell you to step there, but over there. Whats the problem leg?........." I sit, with some humorous difficulty, eat and drink and rest.
Because what faces me is some really serious rock/boulder scrambling. Going uphill all the way to the keyhole.
There is no trail.
