Have a look at the scale of that amount of earth. It's wayyyyyyyyy too big to blow up. Not just the extreme mass of the slide, but its consistency.
There was likely discussions about bringing in a few 30-40 ton excavators and digging a channel to control the water. But from the size of the dig, the water would probably top the earth dam before they could get equipment in and start excavating.
Even if they did get a channel dug, once the water started flowing it would erode the banks and start cutting back the banks etc and creating a bigger problem with unrestricted erosion.. Probably best was to leave it alone and let the water top the dam along the entire face and let whatever channels develop will more gradual.
Time will tell.
But short of a buried nuclear bomb, seriously, you ain't going to move that much dirt with conventional explosives.
Yeah, I can see that, but in my defense I was not thinking blowing the whole slide up just a path where the water could drain . The key point is reducing the build up of water as the bigger that lake gets ... It is a desperate move but I thought they could try something and it would be fun to watch
Start bombing where the lake starts then the waters would rush in
while they bomb a path for the water. It would be a contest between the energy of water vs the strength of the dam
I must sound like Donald Trump when he tweeted the President of France to water bomb Notre Dame , at best such an act would of destroyed the very building they were trying to save
BTW, my proposal is really an exercise in creative thinking,
The rules of such an exercise is no ridiculing allowed as often what seems like a stupid idea can be honed down to something productive
Some of the ideas will be stupid, they are supposed to be, but the exercise is not
It is done all the time in serious think tanks
