The innermost layer was a rabbit-skin blanket — made from the skins of rabbits cut into strips, twisted, and woven into a warm, flexible fabric.

Rabbit-skin blankets and robes were a significant part of the material culture of Great Basin Indigenous peoples, documented ethnographically into the historical era.

The construction technique — the specific way in which the rabbit skins were processed and woven — was recognizable to specialists in Great Basin material culture as belonging to the traditions of the region’s historic peoples.

Outside the rabbit-skin blanket were two tule mats.

Tule — the common name for bulrush, a wetland plant — was one of the most important raw materials for the people who lived around the great marshes and lake margins of the ancient Great Basin.
