Pooh Bear

This image shows the rock called Pooh Bear. Soil found near Pooh Bear seemed to be a clumpy kind; finely grained, cloddy, and rocky. This was different from the soils found near the rock Scooby Doo, which seemed to be a crusty kind, or a rock called the Lamb. These different kinds of soils seemed to be layed down differently.
