Is Steep Holm a roche moutonnee too?

Phil raises the interesting question as to whether Steep Holm is also a roche moutonnee.  It's a much steeper island, but it is elongated in the direction of ice flow (W-E) and has much steeper cliffs at its eastern end than at its western end.  The island is made of Carboniferous Limestone strata, like Flat Holm -- and because the rocks are dipping westwards there is also a strong structural control here.

The interesting thing about Steep Holm is that it is linked to Brean Down near Weston-super-Mare -- and on that particular piece of the mainland there is a Pleistocene stratigraphy that is quite well known.
