Petroglyphs are designs or symbols pecked into rocks.
They are found on boulders and bedrock outcrops on the shore just above or below mean high tide usually near important salmon streams and habitation sites. The rock is metamorphic and tends to be dark gray, fine grained, moderately hard and durable, and highly fractured. Petroglyph Beach in Wrangell has the highest concentration of petroglyphs in Southeast and has recently been designated a State Historic Park. Access to the beach was improved in the year 2000. There is an accessible boardwalk to a deck overlooking Petroglyph Beach, the Stikine River and Zimovia Straits.
