月ノ木貝塚

Nationally designated historic site Tsukinoki shell mound Chiba Prefecture is said to be a treasure trove of shell mounds, which boasts the number one position in Japan. It seems that about 1/4 of the shell mounds in Japan are in Chiba prefecture. It is said that the land where the shells that the ancient people ate and discarded was originally a garbage dump, but is now an important archaeological site. It is a little strange that many shells are piled up here away from the coast, but it seems to indicate that the sea was just below this hill-shaped plateau. In the old days of the Jomon period, the fact that there was a sea for a certain period of time is thought to be a phenomenon called "Holocene glacial retreat". It seems that he was there. At first, the Holocene glacial retreat was thought to be submerged due to volcanic and seismic activity, but since the transgression occurred around the same time worldwide, the theory that the impact of warming is large seems to be predominant. .. A long time ago, I thought easily that if I connected these shell mounds with a line, I could understand the coastline at that time, but it seems that it is not a strong loss, and a diagram showing that situation is also on the net. It is scattered. Roughly speaking, isn't it difficult to understand that Moffmoff's Chiba is in the state immediately after taking a bath? As far as these figures are seen, the Boso Peninsula at that time was almost an island. There is a fairly busy road on the north side of the ruins, and the name of the coffee shop along the road is called "Countryside". If the world is the world, this would not be inferior to the name "seaside". Well, there probably wasn't a coffee shop in the Jomon period.

When Basho was still in elementary school, there was a field in a part of the site here ~ In addition to shells, there was often a heart-shaped arrowhead made of small obsidian on the topsoil of the field! The dark glass-like arrowheads were still sharp enough to cut the skin-it was hard to believe that they were made thousands of years ago ... I think it's still buried in the Tsukinoki plateau.

Cracked shells are already scattered from the entrance of the park It feels strange to see the traces of ancient people. I wanted you to keep the ruins of the house somehow. What? It's so big that it's good for picnics and badminton.
