We explored history in assorted ways when we did the walking tour at El Morro, which is a sandstone formation known for its carved inscriptions that began with ancient native peoples and hosts additions well into the twentieth century. Coolest stop: the kiva in the small excavated area of the Atsinna pueblo ruin atop the landform. Maybe a dozen rooms are on view, but reports say there are something like 875 rooms. That’s a lot of construction! It’s dated to something like AD 1300….
