    I just saw the Dogfights episode "Death of the Luftwaffe" on The History Channel yesterday, and was wondering, what are those "slag heaps" that were seen several times throughout the episode? They were shaped like pyramids and were hundreds of feet high.

    They're the result of mining. Some of the guys who are from mining towns on this board probably know a lot more about it than I but it is the byproduct of sinking shafts into the ground.

    They're pretty common in places like West Virginia and in some places in Scottland.
