A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. The term should not be confused with petrograph, which is an image drawn or painted on a rock face. Many hypotheses explain the purpose of petroglyphs, depending on their location, age, and subject matter. Some may be astronomical markers, maps, and other forms of symbolic communication, including a form of proto-writing. Some petroglyph images probably have deep cultural and religious significance for the societies that created them; in many cases this significance remains for their descendants. Many petroglyphs are thought to represent some kind of not-yet-fully understood symbolic or ritual language.
When Twin Peaks was rerun on the Bravo cable network in 1993, David Lynch wrote new introductions for each episode that were performed by Catherine Coulson as The Log Lady. The one for this episode was thus:
"The beautiful thing about treasure is that it exists. It exists to be found. How beautiful it is to find treasure. Where is the treasure, that when found, leaves one eternally happy? I think we all know it exists. Some say it is inside us--inside us one and all. That would be strange. It would be so near. Then why is it so hard to find, and so difficult to attain?"
