Forgotten petroglyphs in Baltimore park to be studied, displayed

They're well traveled for prehistoric stone carvings, having been moved from the flood-threatened lower Susquehanna Valley in the 1920s, then to various sites in Baltimore, ending up on concrete platforms in eastern Druid Hill Park, all but forgotten in what is now an overgrown space.

And they'll be traveling again to a Calvert County laboratory.

Eventually the more than two dozen Native American carvings, which may be thousands of years old, will be put on display.
