El Morro National Monument
A main east-west trail, dating from antiquity in new Mexico is the sandstone promontory of El Morro. Over the centuries, those who traveled this trail stopped to camp at the shaded oasis beneath these cliffs. They left the carved evidence of their passing -- symbols, names, dates, and fragments of their stories that register the cultures and history intermingled on the rock. Walking around the Loop Trail at the monument, you can see some 2000 petroglyphs and inscriptions that date back to the 1600s when the Spanish traveled through the area.
