  • I have seen a several million year old paleosol on a plateau in Scotland, so it is feasable to find in situ organics in Alpine colls.

  • Could one have had a situation where the 2900-year old trees were destroyed but not uprooted by the 2900-year advance; they were covered up by paleosol in a subsequent retreat, but without trees re-advancing to that elevation in the Roman WP or MWP.

  • We found some pretty neat stuff: a few places with heaps of charcoal and good potential for radiocarbon dates; old tree roots (I think) sticking out of the loess, which could be evidence of the area previously being forested, as they were quite big and can be dated as well; a tall cliff of loess (no rocks!) with a paleosol in the middle.
