The steps were in remarkably good condition. Probably as good as in the day when the Aztec first laid the rocks in place, surrounded them with mortar which they decorated with small stones. It is estimated the pyramids were built sometime between 100 BC and 250 AD. Given the expanse of years and the millions of feet climbing the steps, I have no doubt these have been repaired in modern times. I like to believe, the repairs reflect the style and craftsmanship of the ancients.
