The Yellow trail splits off south from the Red Trail before crossing some open glades. It then goes back into the trees as it descends back towards Woods Fork.hiked this trail with Lanie , I remembered this textured rock and was keeping an eye out for it. A couple of hikes ago I came across a rock that was half covered in lichen. The covered half had these markings, while the uncovered part didn’t lead me to believe that this effect may be caused by the lichen and that the increased foot traffic here has removed it to reveal the pattern underneath.
