Leave historic sites, Native American rock art, ruins and artifacts untouched for the future. Admire rock art from a distance and never touch it. Stay out of ruins, leave artifacts in place, and report violations. The peopel who created this legacy are gone. Now, the phicical remains of their occupation are disappearing at an alarming rate.
Small actions can add up to major damage.
Rock art can be damaged just by touching it. The oil from fingertips speeds erosion by chemically altering ancient painted pigments and the rock itself. Sitting or climbing on rock walls turns ruins into rubble. Walking across middens, the ancient trash heaps below ruins can damage sites. Moving or taking artifacts destroys their scientific value.
