解説：開口部側の壁際で検出された炭化材の様子。写真中央が竪穴長軸の北端に位置する写真6の主柱である。主柱の両脇には、壁面に当てられていた樹皮と、その内側に立てて並べられていた丸太材が住居内部に倒れている様子が確認できる。

comment：Carbonized wood found close to the wall on the opening side of Pit House 7a. The wood in the center of the photograph is the main post (Photograph 6) at the northern end of the long axis of the pit house. On both sides of the main post, pieces of bark, which covered the wall; and logs, which were arranged upright in contact with the wall, are lying inside the pit house.
