5 didn't come up in conversation, but I think you followed my footsteps there. I didn't think I wandered too much, but located it in the same way.
When I warmed down and approached it again, I struggled to descend along the right bank and the hill was directly across the end of the reentrant, so I think that left side flared out a little. (Just an interesting observation)
I've added the splits to AP, if you get a chance it's more interesting with more than one entry;-)
