If that flow was rather big, you could get "icebergs" of solidified lava 
being tossed about
in the molten stream of lava.  (though iceberg would be a poor analogy, 
as few solids
float on the same molten material).  But it would be entirely possible 
for a block of freshly
solidifying lava to get pushed aside and rotated by a lava "river".
