Looking back upcanyon from the Narrows.  A side canyon joins the wash here on  the left.  We dropped our packs and explored up this side canyon.  We didn't notice it at the time but the scratches on the rock behind Gary could be writing - Enlarging the photo, I can make out "Wayne"  on the first line, then .......UR on the second.  I can't decipher the 3rd (Maybe 1934??). - It's definitely not an ancient pictograph but could be historical.
