What crops did the Navajo use?

The Navajo Nation and traditional lands range from 3,500 feet to 10,000 with most between 5000 and 8000 feet and it is 27,000 square miles. That is about the same as Holland and Beligum together. There is a big range in what grows. One of the most common landscapes is steppe land with juniper and pinon pine trees. At higher elvations, with more snow and rain, there are larger pines and firs. At lower areas, there is more of a sagebrush sort of environment. In canyons with creeks there are cottonwoods and sometime gamble oak.
