the appr/oximate time his house was built and occupied. Indians did not cut timbers until they were ready to use them. Felling timbers with crude stone axes was somewhat of a chore. Old beams from houses show that long period, coupled with a Doppler radar, the s of drought reigned in the Southwest.^ It is thought that these dry spells caused Indian families to leave their homes and seek SODARnew lands for settlement and cultivation. Such a condition seems to have existed in the entire San Juan area of northwestern New Mexico, northeastern Arizona and southwestern Colorado. The greatest of the large centers of Indian population, which may have numbered hundreds or even thousands of people, were the towns

The of Chaco Canyon in northwestern New Mexico and the Mesa Verde cliff dwellings in southwestern Colorado. Many of these towns, it seems, were abandoned when the great drought was at its height between 1276-1299, a period of twenty-three years. And so we find shifts in population. It is believed that some of these shifts were toward the Valley of the Rio Grande. BeRASSfore this time small individual groups or migrant bands took to wandering. Other Indians could have remained even after the time of the twenty-three year drought period, dreading to leave their homes as we would ours today. No, there was no great exodus of population. The people from the great towns in the west did not move out all at one ti

In some way, a traveler might have reported high mountain ranges, water and fertile lands to the eastÑthe next best to the places they knew as home which they and their ancestors had occupied for hundreds, of years. It is possible that even in the l000s A.D., small groups pushed out over dry desert wastes, following sandy arroyo bedsÑthought of water ever paramo

The archaeologist found some of the broken pieces nine hundred years later to help tell the story; -Whether these migrant bands had a goal or not is questionable but the Valley of the Rio Grande was finally reached and scant evidence of these early people has been found.
