Notas del editor
- More documentation of the active sand and snow. The upper right photo shows snow on top of fresh sand, which is on top of a frozen crest of sand. The lower left shows a similar sequence, but we didn’t dig down to the frozen crest and note there are more snow layers in the top layer.
- The following are pictures documenting the deposition of sand on the lake ice of Lake Michigan showing that the sand is indeed blowing on the lake. Here you can see the dunes in the background with the sand along with some snow deposited here on the ice
- Radiocarbon dates were obtained from 3 locations throughout the unit to aid in comparison to the Baedke and Thompson curve. When these results were compared to the Baedke and Thompson curve, there appeared to be a positive correlation between high lake levels and high sand percents.
