Pueblo Bonito, probably the largest single prehistoric Indian building in the Southwest at the time it was constructed, represents the highest development of Anasazi architecture. Most of the construction was between the years A.D. 1030 and 1079. The bulk of the wall’s thickness was made up of rough, unshaped random stones laid in mud mortar. Then the walls were veneered, inside and out, with the carefully fitted stone you see here. The stone used for the facing, a hard, dense sandstone, was quarried from a narrow band of rock at the top of the cliff behind the pueblo. So much of this stone was used to build the great houses of the canyon that most of it has been removed for a mile east and west of Pueblo Bonito, but in other places the signs of ancient quarrying are still evident.

The small, rectangular openings in this wall were vents for air and light in the lower rooms. The round holes are sockets for vigas, ceiling beams.

The large, broken stones here and to your left are what remain of Threatening Rock, a large vertical slab of native rock which once stood separated from the cliff by a wide crack. The people of Pueblo Bonito felt the threat of its fall, for using posts, mud, and stone masonry, they attempted to shore up the rock, or to prevent erosion of its base. Here you can see a remnant of that early attempt. The Navajos, who were not here until long after the last of the Anasazi departed, call Pueblo Bonito “the place where the cliff is propped up”, and they relate a tale about their predecessors pouring baskets of turquoise and white shell behind the rock as an offering to the spirits to prevent its fall. When the huge slab finally came down in January 1941, no turquoise was found, but it was discovered that the Anasazi had placed prayer sticks behind the rock. These are peeled and carved willow wands, painted and decorated with feathers, which are still used by Pueblo people somewhat in the way altar candles are used.
