The signal part was actually the rock art
left by Native Americans that travelled through the area and left
signals to others. I was expecting to see one or two faded petroglyphs etched into the rock but was I ever surprised. There
were hundreds of them and all very well preserved for the 600 (or even
1500) years they've been there. And despite visitors having easy
access to them, the petroglyphs seem to be rather undisturbed. I
think that could possibly be from a
sign
well-placed by the NPS. |
