How did the Dead Sea get so salty?

Why is the Dead Sea so salty? Much of the salt content of the Dead Sea comes from the rocks eroding on the shores. The shores are made up of rock salt and other rocks with a high mineral content. As the rocks and the salt erodes from the shores the stuff that makes up the rocks ends up in the water.

You can't walk on the water of the Dead Sea. The water is rich in salt and minerals, so it has a silky, thick consistency that will keep you afloat if you're swimming. But the buoyancy is not enough to walk on. You can, however, walk on large slabs of solid salt that form in the water, and along the shore.
