I've been on a quest to find out why my sandy sub soils are so moist, while other's are excessively drained. When Stu was over, I showed him the bottom of a blow down stump which to me looked like solid sand - but I've discovered it's not. If that were the case, it not only wouldn't have turned to near rock once it dried, but it also wouldn't remain suspended in defiance of gravity. There's more silt/clay in it than that - so now I'm wondering exactly how much?
I'm also trying to learn if there's a way to "pull the cork" on my swamp since the township is un-motivated to remedy my excessive water table (caused by a poorly placed culvert). When the DNR guy did some deep samples, he pulled out a layer of green clay beneath the muck which had sand under it. I'm contemplating doing a little auger probing of my own to see about making it better drained. I'm losing my mature trees due to the water table being raised a foot higher than it's been in the past 50 years anyway. The swamp acts as a run-off sediment basin before running into the lake, but since the road has dammed it, there's a lot of water retained that shouldn't be there.
