Moraine deposits left when a glacier melts will generally be.....?
Well, think about it for a second. Moraine deposits are basically just the stuff dumped out of the ice. It isn't moved after it falls out of the ice. Therefore sorting by size is not to be expected (although I suppose some size sorting on the flanks may occur due to gravity separation as the mounds settle).





Would layering be expected? Why does layering occur? The absence of large changes in the way the sediment accumulates and absence of sorting processes would make any fine bedding very unlikely. I suppose a grosser "bedding" could occur, but generally this would not be expected either.





Generally, moraine deposits are similar to what happens when one takes a dumptruck full of dirt and empties it in a spot. You wouldn't expect much layering or bedding. Even dumping a bunch of truckloads of dirt doesn't result in any real bedding, although with careful excavation you might be able to identify separate truck loads if you are lucky.
