Adobe Bricks

The walls, as a rule, were made of stone; indeed it is unusual to find adobe walls in cliff-dwellings of the Mesa Verde. In prehistoric buildings in our Southwest, evidences that the ancients made adobe bricks, sun-dried before laying, are very rare. Bricks made of clay are set in the walls of the Speaker-chief's House and were found in the fallen débris at its base. These bricks were made cubical in form before laying, but there is nothing to prove that they were molded in forms or frames, nor do they have a core of straw as in the case of the adobes used in the construction of Inscription House in the Navaho National Monument, Arizona.[24] The use of adobes in the construction of cliff-house walls has not been previously mentioned, although we find references to "lumps of clay" in the earliest historic times among Pueblos. Thus the inhabitants of Tiguex, according to Castañeda, were acquainted with adobes. "They collect," says this author, "great heaps of thyme and rushes and set them on fire; when the mass is reduced to ashes and charcoal they cast a great quantity of earth and water upon it and mix the whole together. They knead this stuff into round lumps, which they learn to dry and use instead of stone."

Attention may be called to the fact that not only the adobes found at Cliff Palace but also the mortar used in the construction of the walls contain ashes and sometimes even small fragments of charcoal. Clay or adobe plastered on osiers woven between upright sticks, so common in the walls of cliff-dwellings in Canyon de Chelly and in the ruins in the Navaho Monument, while not unknown in the Mesa Verde, is an exceptional method of construction and was not observed at Cliff Palace. The survival[25] of this method of building a wall, if survival it be, may be seen in the deflector of kiva K.
