No hunter could have seen it, or suspected it from that side.
"This is Grand Canyon country, an' nobody knows what he's goin' to find," was Frank's comment.
"Now we're in Nail Canyon proper," said Stewart; "An' I know my bearin's.

I can climb out a mile below an' cut across to Kanab Canyon, an' slip up into Nail Canyon agin, ahead of the mustangs, an' drive 'em up.

So all you need do is go below the break, where I climb out, an' wait.
