How did wooden equipment not whither away in 7000 years?

- teepo 2mo agoI have the same question - My guess is at that altitude, temperature, and under an ice sheet, and silt until the lake was drained. Here's the paper: https://www.cambridge.org/core/journals/antiquity/article/introduction-of-fish-to-the-scandinavian-mountains-by-hunterfishergatherers-5000-bc/29BD68BA540BA600E05E867CBDF4C6D9 https://www.cambridge.org/core/journals/antiquity/article/in...
- marking-time 2mo agoArtifacts that survive this long are usually found in a buried context, which can, under favorable conditions, preserve them for long periods of time. The artifact can be buried by colluvial(gravity driven), or alluvial(water driven) deposition before they have a chance to decay. For more information you can consult a geomorphologist, which I am not.

- ErroneousBosh 2mo agoIn the peat bogs on Skye where I grew up and where people still cut peat for fuel, you often see the remains of silver birch trees that must have grown a couple of thousand years ago. They're often so well-preserved that not only can you clearly see the markings on the bark but you can sometimes make out the rings in the wood. I remember my dad pulling out a piece that was so well preserved you could see where deer had gnawed it.
