Impossible? Apparently not..... (modified)

On one of the discussion threads recently somebody said that it was impossible for morainic features to cross one another.  Well, it's not impossible.  I have seen morainic features that intersect, in response to shifting ice edge positions -- for example around the snout of a small glacier.  Here is another interesting example from Bruarjokull in Iceland.  What we have here is a fluted (ground moraine) feature running from the foreground and to the left of the girl, and crossing it at right angles is a crevasse fill -- typical of something that forms in a heavily crevassed and dirty glacier that is wasting rapidly.  Neither of these features on the ground has anything to do with a previous ice edge position.

Also,  notice the scatter of erratics in the background -- the definition on this pic is very good -- just click on it for enlargement.

Postscript

I'm not going to get sucked into one of those interminable exchanges with Kostas here, but as an aid to universal enlightenment here is a map of Wisconsin moraine positions in Illinois.  Note that there are many intersections of moraines.

 The reason for these intersections is that when an ice sheet edge is retreating across a landscape it is very rare for the whole ice edge to retreat at the same rate.  Indeed, there may be short-lived advances during the course of an overall retreat.  These small advances will of course have different dynamics in them -- and the ice streams may come from different directions from those of the earlier ice sheet.  So moraines get truncated and overridden. Hence intersections.  Perfectly simple.
