Must have been quite a Flood.

[SES1066]

Some of the largest tsunamis known have been generated within closed waters where the amplitude of the wave is created because of the constriction of the geography. In 1958 (07/09), an earthquake caused a landslide into Lituya Bay in Alaska, a constricted fiord bordering upon 3 glaciers in the southern panhandle. The resulting wave reached a height of 1,720 feet (524 m) as measured by the affected foliage. This is the world record for a historical tsunami.

This gives a whole new meaning to that common term, "100 year flood", doesn't it?

“Chalcolithic Catastrophe”

Sounds like a Ben and Jerry’s ice cream flavor.

This whole copper thing has fascinated me for years. When I was a Kid I was taught that some WOG discovered it in his camp fire. Wilhelm Von Loon.

So I conducted an experiment, while working for a very large company that gave me little to do under slack supervision.

I built a furnace of refractory brick, several bricks stacked in a circle with a small opening on side. The crucible was a 6” steel cap.

I took some scrap copper and tossed into the pot and applied 3000 degree heat from an H2O2 torch. No melt after Eight hours.
