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.
Did You Know?
Early Spanish travelers called the questa El Morro, which is Spanish for the headland or the bluff. Subsequent American travelers referred to El Morro as Inscription Rock, but when it came to naming the National Monument in 1906, the earlier Spanish name persevered.
