Contest #161 answer: Lago di Lei, Swiss/Italian border

In the Valle di Lei, an Italian uninhabited valley in the Alps, lies the Lago di Lei, where the Italians constructed a hydropower dam in the years 1957-1961.

In an Italian/Swiss exchange of territory in 1962-1963, just after the completion, the dam and power station was assigned to Switserland.

I could not find more information about the backgrounds of this border rearrangement, so if anyone here can shine more light on this matter, please feel free to do so in the comments.

Contest #160 answer: San José Mine, Copiapó, Chile

Again we looked at a current event: the miraculous rescue of the 33 miners who were trapped underground for 69 days in the San José Mine near Copiapó, Chile.

I think half the world witnessed the drilling and rescue operations, which saved the lives of these 33 miners.

This ends the current series, were we experimented with the new ‘Hint’ system. And your reactions are unanimous: We are keeping the hint system as it is now.

This series had a clear winner: hhgygy with 19 points. Congratulations Horváth!

Do you like the new ‘Hint system’?

This series is almost coming to an end, so the question here is: How do you rate the new ‘Hint system’, officially introduced with Contest # 152. Should we keep it this way or not?

Please give your opinion in the comments of this post.

Thanks.

Contest #159 answer: Alumina waste disaster, Ajka, Hungary

This one was hardly to be missed: This is the waste storage of the Timföldgyár Alumina plant in Ajka, Hungary that broke loose.

As a result the nearby towns of Kolontár and Devecser were flooded with a red toxic mud.
