Little Hawk and Guest/999, when you get done moving the Rockies you will probably want a lake, a really big lake. I have just the know how for it.

Wait 'til the dead of winter when the shallow waters are frozen all the way down. Get a lot of trucks and a big crew with a bunch of chain saws and set to work. Haul those slabs and chunks out on the trucks and drive them to some hole in the ground where you want them. Then dump them.

Come spring, you'll have yourself a big lake.

Don't thank me. I'm happy to do this just for you.
