Thanks for the notes.
I had a pretty light pack – burros had the heavy stuff. And I do a lot of similar hiking all year. Not that the first time can’t occur. . .
On the ascent I turned around as I was getting early signs – big headache, dizzy, and the stomach starting to head towards nausea – given the location with pretty much zero extraction possibility that was enough of a signal to stop.
Unless that last paragraph suggests something else I’ll leave it at a new unrelated effect I’ll probably have again, if the cerebral signals imply something else that would be interesting.
Thank you again.
