There are 1,388 known sites within the burned area of the park. Because ancient buildings in the area are made of sandstone, the fire was capable of significant damage. According to Morris, the intense heat of fire causes spalling in sandstone. Fires burned all sites on Wetherill Mesa, coming right up to the doorsteps of Long House and Step House, two important cliff dwellings, after destroying modern-day facilities including rest rooms and the ranger station. Besides damage to sandstone architecture, artifacts were greatly affected.
Work is far from over, despite the fires having been contained months ago.
Their focus is on both natural and cultural resources. The worst problem the team faces is erosion. Workers are creating channels and dams as well as trying to break down the fire-traumatized soil so it will accept water. If water does not absorb into the ground, then it flows over the land, down slopes, and washes away archaeological remains. In addition to protecting sites, scientists will have to account for new finds.
