"Walking It Off," the book of memoirs by Doug Peacock,
describes in detail walking through the Cabeza Prieta.
This is the conclusion of Peacock's book.
I don't know, but I have my suspicions
that the narrative at that point,
which chronicles a single journey,
in real life is the conflation of repeated visits over time --
that not everything that transpires on that walk
happened on one and the same walk actually.

That's as close to Mr. Abbey's grave
as I will ever knowingly get.
I'd rather read his books.
To misquote an old cowboy remark,
"you can do it in the shade."
