True, but the hallmark of glacial erosion is shattered rock. Jumbled bolder fields and rock of different layers jumbled together as they were bulldozed down the slope. Its the opposite of the smooth folds being discussed in the original post.

You do get some sedimentation from glacial till, rock powdered much finer than talcum powder. But it ends up in perfect horizontal layers at the bottom of lakes and oceans. If you try to bend it it while still submerged it just puffs up into silt and then settles out horizontal again. It has to get dried out and compressed before it becomes rock again.
