ancient character writings (Oregon)

You already know who sent this terrific postcard; it could be none other than Linda! She writes that her holiday decorations are up and she’s seeing a few friends here and there already.

The postcard itself says: “Ancient Character Writings removed from cliffs along the nearby Columbia River and brought to Ginkgo Petrified Forest Museum to make a most unusual display. They are believed to have been made many hundreds of years ago by migrants from Mexico or South America where these characters are common.”
