The earliest people to inhabit this area were called Basketmaker. This was because they wove distinct baskets. They grew corn, squash, beans, and tomatoes that they acquired
by trading with Mexico. Then sometime before 500 AD it began to rain more often making it easier to grow vegetables. As a result they prospered and there was a population boom. Soon people began living in pit houses next to their storage rooms. Then between 500 BC and 600 BC people began living above the ground in one story buildings.
