Conservation image Maya Initiative (1999–2009)
A project of the Getty Conservation Institute

Over the years, the deterioration of the stone has been a major cause of concern because it directly impacts the readability of the glyphs. The stone blocks, which are made from volcanic tuff, have been exposed to natural and human actions and show significant signs of decay. A careful study was undertaken to better understand the condition of the Stairway and its causes of decay. Photo: David Carson.
