little b, I’ve heard of moraines which I believe are the ridge of debris that the glacier bulldozes along the front edge . I haven’t heard of an esker . But that’s hardly surprising when in the notes it states the most famous is actually called an EISCIR !! Make up your mind and phrase the question properly!
