which canyon do the directions lead to?

[don]

the directions on ruths map..i.e “the first gorge on the south side, from the west end of the range” – they found, as he
had told them, a monumented trail which led them “northward over a lofty ridge; thence
downward past Sombrero Butte into a long canyon running north, and finally to a
tributary canyon very deep and rocky, and densely wooded with a continuous thicket of
scrub oak.”
following these directions ,to which canyon would it lead? or are there numerous possibilities? are the directions too vague? now im not suggesting the directions have any validity,in fact im assuming they dont ,else we would all know which canyon it refferred to,i suppose. but to me ,a person whos never visited the superstitions, the directions appear to be clear enough.
kind regards
