説明
宮本遺跡は、おもに6千〜4千年前頃（縄文時代前期〜中期）に利用されていた遺跡です。昭和58〜60年に自由が丘団地を造成するときと、平成5〜6年に帯広国際センター棟を建設するときに発掘調査が行われ、たくさんの土器・石器類とたて穴住居跡、貯蔵穴、落し穴などが見つかりました。
落し穴は長さ3m、幅1m、深さ1m前後の細長い形で、単独または列状に並んで19基ありました。シカをとるために設置されたものと考えられています。
またこの遺跡では、木の実などをすりつぶす道具（すり石）もたくさん見つかりました。植物質の食料が大量に加工されていたこともうかがえます。
Miyamoto Site is an archaeological spot which was frequently used by prehistoric people between 6000 and 4000 years ago. This time period is considered the early and middle "Jomon" period in Japan, an era characterized by the first hunte - gatherers who made pottery.
Excavation was conducted from 1983 to 1985 (during the Jiyugaoka housing construction) and from 1993 to 1994 (during the JICA Hokkaido International Center (Obihiro) construction). Evidence of pits used for trapping, dwelling and storage were found. Artifacts such as pottery shards and stone tools were also found.
An important finding was the trapping pits. 19 pits (3 m in length, 1 m in width and about 1 m in depth) were found, with some in rows. It is believed that they have been dug for deer hunting.
Another interesting finding was the many stone tools which were used to grind edible plants and nuts. This suggests that a large amount of plant - based foods was processed in this site.
