Switzerland offers $60K cash prize for ideas to rid its iconic alpine lakes of military ammunition

• Switzerland is offering a cash prize for solutions to remove munitions from its lakes.
• The ammo was dumped in lakes between 1918 and 1964 as the Swiss military believed it to be safe.
• Any salvage operation is expected to cost billions, the BBC reported.

Tourists heading to some of Switzerland's most iconic lakes may be surprised to learn that thousands of metric tons of ammunition lie beneath those picture-perfect waters.

And the Swiss government is now offering a reward for the best ideas to get it out.
