This is the book. It seems to be pretty comprehensive.

As confident as I am that not only myself, but everyone in the group could handle it, doing it for the first time completely solo doesn’t seem like a good decision. If we don’t end up doing it this time, I’ll be back within a few years, either with a group that is comfortable with it or the same group if they eventually come around. One way or another, I will be getting it in soon.

On the ledges, we are doing this over the course of 3 days for two reasons. One, we’re coming from 3,000 miles away to do it and want to take it all in at a leisurely pace to get good photography and enjoyment along the way. And two, to acclimatize slowly, as we live at sea level.

We are spending one night prior to hitting the trail at either onion valley (12,000’) or the portal(8,000’) to begin the process of acclimatizing.

I worry about going right from sea level to staying the night at 12,000’ at Onion night one. Seems like too much, too soon, for too long to me and would seem to be asking for trouble. But again, I was outvoted. My preference was to stay further down the portal road at 6,000’ night one before hitting the trailhead the next morning.
