Underneath the top of the rock we partially removed was about five pounds of HE. Another five pounds were put on top of it and a detonator target put on top of that.

Another detontor was put on top of the previous one to make it visible from our shooting position. The plastic jugs have water in them to help direct the blast into the rock.

Rock two.
There is about 20 pounds of HE underneath the dirt and jugs of water. There are four detonator targets stacked on top of each other to get down to the main charge. This gave us enough height to see it from our shooting position.
