Repair of Walls
The masonry work necessary to repair a ruin as large and as much demolished as Cliff Palace was very considerable. The greatest amount was expended on those walls in front of the cave floor hidden under the lower terraces, at the northern and southern extremities. The latter portion was so completely destroyed that it had to be rebuilt in some places, while at the southern end an equal amount of repair work was necessary. ([pls. 3], [6], [7], [9].) To permanently protect these sections of the ruin the tops of the walls and the plazas were liberally covered with Portland cement, and runways were constructed to carry off the surface water into gutters by which it was diverted over the retaining walls to fall on the rock foundations beyond. It would be impossible permanently to protect some of these exposed walls without constructing roofs above them; at present every heavy rain is bound to cover the floors of the kivas with water and thus eventually to undermine their foundations.
The preservation of walls deep in the cave under protection of the roof was not a difficult problem. The work in this part consisted chiefly in the repair of kiva walls, building them to their former height at the level of neighboring plazas.
