Best I know, Jim, moraine is the debris left behind as a glacier melts. In
the case of Moraine Lake, I would guess it's terminal moraine which lies at
90degrees to the direction of flow of the glacier, as opposed to lateral
moraine which lies along the edges, parallel to the direction of flow. Thus
neither quake- nor landslide-related, but it's easy to see how you might
think so.

And isn't Moraine Lake in Alberta of similar origins? At least a large land
slide, maybe or maybe not associated with an earthquake.
Scott: Which lake N of Mt. Rainier? You know, there are still standing
timbers/remnants of shoreline forests at the bottom at Lake Washington
(South end at least) that are the result of the lahars/mud flow from it's
last eruption.

Yes, all the schools that collapsed, why?
As many had stated, they are allowed only one child and many are too old
to have another one now, which has to be doubly painful.
There are quake lakes in the Pacific Rim of Fire, but the ones I have been
shown are really old, newest ones are like several hundred years old, though
some were caused by volcanic eruptions and the debris gouging out a lake. I
grew up next to one of those, 30 miles north of Mt
Rainer from it's 1820/54? Eruption.
