-
A further 29 recently deposited ice-proximal stimps rooted within a well-preserved paleosol were located 50 to 150 m downstream on the adjacent outwash surface.
-
Which makes it odd how a paleosol figure 2 can survive so unharmed in a moraine.
-
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.
-
The area in red is the region of the paleosol with the tree stumps, this area was likely not covered by ice since the last ice age.
-
When first examined in early September, erosion through a 3- to 5- m sequence of glacial outwash and overlying till had exposed 17 sheared stumps rooted within a well-preserved paleosol Figure 2.
-
Maybe the medieval paleosol was bulldozed by the big LIA glacial advance so that the vein was exposed when the LIA glacier retreated and is visible to a modern prospector, but would not have been visible to a medieval prospector.
-
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.
