Rescue excavation in autumn 2020 of a 7000 m² plot in Plouharnel, 2 km west of Le Ménec: a Late Mesolithic hut, a pre-megalithic mound with a dry-stone cist, foundation pits for at least two rows of standing stones, and cooking pits. Forty-nine radiocarbon dates on short-lived charcoal from 33 features, modelled in OxCal with outlier analysis, give six phases from 5700 to 4050 cal BC; the standing stones went up between about 4670 and 4250 cal BC. **Carnac alignments** ArticleCopy of **[Standing-stone foundation pits with wedging stones, Le Plasker](https://mysteriesdept.com/mysteries/carnac-alignments/artifacts/ART0D69TN926KXH/standing-stone-foundation-pits-with-wedging-stones-le)** doi: **[10.15184/aqy.2025.10123](https://doi.org/10.15184/aqy.2025.10123)** Checked against the original0 ## What it's used for here The first modelled radiocarbon chronology for a section of the Carnac alignments; source of the dataset. ## The document 20 pages [Pages][Text]Page 1 of 20 [![Page 1](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p1)1][![Page 2](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p2)2][![Page 3](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p3)3][![Page 4](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p4)4][![Page 5](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p5)5][![Page 6](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p6)6][![Page 7](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p7)7][![Page 8](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p8)8][![Page 9](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p9)9][![Page 10](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p10)10][![Page 11](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p11)11][![Page 12](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p12)12] ![Page 1 of Le Plasker in Plouharnel (fifth millennium cal BC): a newly discovered section of the megalithic complex of Carnac](https://mysteriesdept.com/files/v/bc4482451e8ceb3b0fc98a95580f4e8ba003022b5cab98d068d1954f8c17582b/p1) The first 12 pages are shown; the rest are in the file.
