Best Answer

A Boulder, or Talus, Cave is simply an enterable void or set of voids between boulders and the rock-face from which they have fallen.

Collapses within existing karst, sea or lava caves may choke the passage or chamber with boulders, and such chambers are often called "boulder chambers", but that does not form the cave, and it is not the same as a true boulder cave.

Ridge left by a glacier?

The ridge formed from till deposits at the edge of a glacier is called a moraine. It may be formed from glacial flours or from large boulders.


Boulders carried many miles by a glacier are called?

Boulders that have been carried by a glacier have a couple names, but most commonly they are referred to as glacial boulders or erratics. If you're interested in learning more about glacial boulders, the Iowa Department of Natural Resources has a pretty good article about them; as Iowa and most of the American Midwest were covered by glaciers during the last Ice Age, glacial boulders are fairly common there. http://www.igsb.uiowa.edu/browse/boulders/boulders.htm

How can an esker be quickly differentiated from a moraine by its sediment?

Since the esker was deposited in a flowing water regime, I would not expect to find many fine clays there. And I would not expect to find any large boulders, >1m in an esker. The moraine on the other hand will have parts that have been formed by rocks grinding each other in a comparatively waterless regime. So it will have lots of fine clays. Boulders >>1m could even be a feature of a moraine.
