During a rest break in Behind the Rocks I thought I spied a petroglyph on a boulder. With binoculars I thought for sure the design had to be man-made. It just so happened that the boulder was very close to the route I had planned to take to reach my goal, so it was easy to make a slight detour to check out this discovery.
The effort was for naught as the "petroglyph" was merely a collection of erosion pits in the rock. The black bands on the bambnoo hiking stick are 12 inches (30 cm) apart.
