As you wander around the Western Front you will occassionally come across these huge craters. Onkay, the weather has worn a lot of them down, but many of them are so deep that they have basically become a part of the landscape. Many of them were created by soldiers tunnelling under the ground and the packing the area with huge amonts of explosives, and then setting them off. The sad thing is that despite all of the effore they rarely did any good at all. However, a number of these craters have been left to the ravages of time, while others are preseved, such as this one, as a memorial to the horrors of war.
