Rising prices are very bad for someone who is betting that the price is going down, especially when the time for settling the bet is coming due, so they tried to buy up a bunch of nickel to cover their bets, which drove the price up even higher and eventually the London Metals Exchange said this is crazy and shut down all nickel trading. It looks like the Chinese producer is going to be out $8 billion which is no small amount, even for a Chinese oligarch.
Norilsk is the site of Russia's biggest nickel mining and smelting operation. It is pretty well landlocked, so their product is shipped to 50 miles to Dudinka where it is loaded onto ships on the Yenisei River.
Dudinka is 1.5 degrees north of the Arctic Circle, so the
Yenisei River is a river of ice, which makes shipping a challenge, to put it mildly.
All those colored dots on this map are big ships. Norilsk is near the right hand edge of the map and the green dot about a half of an inch to the left is at Dudinka. Left of center in the image is another river of ice but it has quite a bit more traffic. I wonder what they are doing over there. I imagine more resource extraction, but that's going to have to wait for another time.
I did this puzzle a couple of days ago and I wondered where the photo was taken. Didn't find anything, I suspect it's in Alaska, but who knows. I'm tacking it on here just because it seems to fit.
