[Rockhounds] Death Valley's Racing Rocks

[Kay Davis]

That would only be true if the ice grew until it pushed the rock... but if
we think of a bearing race where the ball bearings are surrounded by the
race, Ice could easily do the same and would not have a leading edge to be
pushed down by the rock...

Sounds like a good theory, but wouldn't the edge of the ice leave some sort

of mark on the lakebed as well?
