There were other Indians who preferred to build their homes on the high mesas during these early times. Adobe was used almost exclusively to build the low walls of rooms. Some bedded small stones into the walls before they were dry. This helped to hold them together. Others preferred to use larger stone, picked up at random, in building their house walls. The adobe huts were undoubtedly unsatisfactory because of their low resistance to weather. Since older styles of pottery have been found in the ruins of these houses, it is logical to suppose that Indians migrating onto the Pajarito built adobe houses first. Later they dug themselves out homes in the cliffs which gave them greater protection from the weather and from any invaders. In this wilderness a mule deer could have fed in a little valley or drunk from a creek. This would mean food for the entire family or group if a crude arrow would hit its mark. Small razor-sharp fleshers of chalcedony or basalt were used to remove the hide from the carcass. The hide could be used for making clothing or moccasins. Some of the smaller bones might have been used as drills and awls until better ones could be obtained. A flock of wild turkeys would have solved this problem. Turkey bones made excellent awls. Just what the people used for arrow points during these early times is questionable. Maybe they brought them along from the west. They could have used chipped chalcedony or basalt which was readily found, and quite common in this area. An occasional nodule of black volcanic glass, called obsidian, washed down the creek and was found bedded in its soft sandy bottom. Obsidian might have been more popular during later times as the early dweller in this country may not have discovered the ledges of black glass immediately upon his arrival. Such could have been life on the Pajarito Plateau eight hundred years ago.
