The inscriptions and petroglyphs at El Morro are a part of our heritage, and although they are very old, they will not be here forever. Sand grains are washed away, rocks crumble and fall, and lichens and clay deposits cover the historic carvings.
These first, well-intended though intrusive attempts to preserve the inscriptions ended in the 1930s, though even today you will see remnants of the darkening technique in some of the Spanish carvings.

The Headland Trail at El Morro National Monument was hand-carved into the sandstone by a Civil Works Administration (CWA) crew in 1933. CWA was one of the New Deal programs initiated by President Franklin D. Roosevelt during the Great Depression.
