Incredible documentary which covers the Rissa Landslide of 1978, shows how soil mineralogy, groundwater, sedimentary deposits, sea level change, and human development all came together to create one of the most spectacular and unintentional landslides in the 20th century to ever be caught on camera. This is a truly magnificent documentary that anyone interested in geology should watch.

There is an interesting type of clay - called "A Quick Clay" - A nice clay, very friendly and adds a youthful appearance etc.
BUT under certain circumstances, "Woe betide thee."
The very simple story is, it's one of the ultra low salt clays.... as the dissolved salt or the almost complete absence of, has an incredibly strong effect on the fluidity or lack of, of the clay.
There is a remarkable decrease in ignorance today.
And this is what I mean when there are things that they are beyond "tripping" - at 8:28 plus... "Whoaaaaaaaaa Far Out!"
