函館の縄文・大船（おおふね）遺跡 （４）
Today I would like to introduce you to the Ofune site in Hakodate (4)
この大船遺跡は食料調達の関係から、大船川の段丘上にある。
The Ofuna site is located on the terraces of the Ofuna River for the purpose of food procurement.
100棟を超える竪穴建物跡と大規模な盛土（捨て場・祭祀の場）が特徴
and is characterized by the remains of over 100 pit buildings and large scale fill (dumping ground and ritual site).
特に私が驚いたのが、
深さ2ｍ、直径10ｍを超える大型竪穴住居跡だ！
I was particularly surprised to see the remains of a large pit dwelling, 2m deep and over 10m in diameter!
竪穴住居の平均的な深さの4倍！直径は2倍に達する！
Four times the average depth I've seen! The diameter reaches twice that!
この集落が営まれたのはBC3200～2000年（縄文時代の前中期ごろ）
This settlement was built between 3200 BC and 2000 BC (around the middle of the pre-Jomon period).
地中には、まだ未発掘の住居跡がたくさんあるらしい
Apparently, there are still many unexcavated remains of houses under the ground!
大規模な盛土遺構は「捨て場」としての機能と死者をあの世に送る祭祀の場であった可能性が指摘されている。
It has been pointed out that the large-scale embankment remains may have functioned as a "dumping ground" and a place for rituals to send the dead to the afterlife
出土遺物は約20万に達し、クジラをはじめとする海の大型生き物や2000を超える石皿などが出土。
About 200,000 artifacts have been excavated, including whales and other large sea creatures, as well as more than 2,000 stone plates.
出土品は函館市縄文文化交流センターに展示されている。
The excavated artifacts are on display at the Jomon Culture Exchange Center in Hakodate.
