Such was Old Marble Mine Road, which he followed up into the mountains between Pina2bo and the river one day, for no other reason than he liked the sound of its name. According to the nav system it would eventually terminate in a sort of box canyon just below the crest of the range.

The overall direction of movement was a little west of due south, but along the way it managed to veer through every other point of the compass.
