Basketry

The
finest Ancestral Puebloan baskets were produced at an early stage of
their culture before they started making pottery. Using the spiral twilled
technique, they wove handsomely decorated baskets of many sizes and
shapes and used them for carrying water, storing grain, and even cooking.
They waterproofed their baskets by lining them with pitch and cooked
in them by dropping heated stones into the water. The most common coiling
material was split willow but sometimes rabbitbrush or skunkbush was
used. After the introduction of pottery about A.D. 550, the quality
and quantity of basketry declined.
