...was the south fork snoqualmie, fall in the wall section @ 1100cfs.

Usually it's only run at 300-500, yeah, we were on it pretty high.

The hole was the bottom ledge of the drop two drops below the fearsome foursome, I don't know it's name or whether it has one even.  That last ledge is pretty unpleasant there on the left, be sure to scout and set safety if you run this stretch above 550.
