comment：Eastern area of the bone mound found in the innermost area of Pit House 10a. The back of the photograph is the innermost side. Although the majority of this bone mound consisted of brown bear (Ursus arctos) long bones and trunk bones, there were no brown bear skulls. A few other animal bones, such as sea mammal and bird bones were also found.
