The Loess Itself...
- Loess, such as that shown in the bluff at the right (notice the interesting bee-tunnels... ), is composed of tiny mineral particles with very specific characteristics
- A sharp scientist decided that snails were telling us loess's story
- Despite the clear message from the snails, for a long time the debate continued over where loess comes from
- Why is our loess located where it is?
- The age of our loess has been determined, thanks to C14 and... snails
Loess & the Ice Age...
- Putting our loess's age into the context of time
- Our loess was deposited during the last Ice Age

Just below the Loess...
- What's the story of the sand and gravel below our loess?
- What if we dug a hole through all the loess, sand and gravel, and kept on going for thousands of feet deeper?
- Sometimes, in the rocks below the loess, sand and gravel, there's a whale of a story
