Site 18

Site 18 is about 9.4 miles from the Minnie Maud bridge and is about a half mile short of Argyle Canyon.  At the intersection of the Argyle canyon road, reset your odometer to zero if you do not have a GPS unit and/or the Spangler book.
This site is right next to the road at ground level and a word of caution:  One of the figures on the panel might seem to be pornographic to some individuals.
