Most of the world's caesium is in a lake in Manitoba The best-known use of this element is in caesium-based atomic clocks — which are so accurate they would only be off by two seconds over a 65 million year lifespan. It's also used as a lubricant for large drilling projects. The world's richest deposit of caesium (roughly two-thirds of it) is at Bernic Lake, Manitoba.
