Tabeguache Cave
In the Tabeguache drainage of southwestern Colorado have been found caves containing stratified deposits, the lowest of which are believed to be quite old although considerably more recent than the really ancient cultures previously discussed.[66][67] These deposits contained lined and unlined firepits and there were little holes, dug in the cave floor, filled with ashes and charcoal. These are thought to have been too small to have served any utilitarian purpose and it has been suggested that they may have been ceremonial in nature. Also found were grinding stones and a distinctive type of long slender [projectile point] with side notches to which the name Tabeguache Point has been applied. There was no pottery.
Obviously, a great deal of work will have to be done and probably many years will elapse before we have any clear picture of what was happening in various parts of the Southwest prior to the time to which we assign the letters A.D. If only all the descendants of the first people had stayed in the same place and placed their cultural remains neatly on top of those of their ancestors, archaeologists would find everything more simple, though probably rather dull.
