area of the Rocky Mts. to the Southwest and included much of California. Typical tribes were the Spokan, the Paiute, the Nez Perce, and the Shoshone. This was an area of great linguistic diversity. Because of the inhospitable environment the cultural development was generally low. The Native Americans in the Central Valley of California and on the California coast, notably the Pomo, were sedentary peoples who gathered edible plants, roots, and fruit and also hunted small game. Their acorn bread, made by pounding acorns into meal and then leaching it with hot water, was distinctive, and they cooked in baskets filled with water and heated by hot stones. Living in brush shelters or more substantial lean-tos, they had partly buried earth lodges for ceremonies and ritual sweat baths. Basketry, coiled and twined, was highly developed. To the north, between the Cascade Range and the Rocky Mts., the social, political, and religious systems were simple, and art was nonexistent. The Native Americans there underwent (since 1730) a great cultural change when they obtained from the Plains Indians the horse, the tepee, a form of the sun dance, and deerskin clothes. They continued, however, to fish for salmon with nets and spears and to gather camas bulbs. They also gathered ants and other insects and hunted small game and, in later times, buffalo. Their permanent winter villages on waterways had semisubterranean lodges with conical roofs; a few Native Americans lived in bark-covered long houses.
