some kind of muck i've never seen before

I hear ya on clearwater lake.  They should change the name of the lake.. Ha, Ha.. 

Part of this video shows some good shots of the quick sand, and it looks like flowing water in a stream.  It appeared to be running down the bank, like it was never ending, and sliding down to the bottom.

Pretty cool, any way you take it.
