*My guess for the cause of these, ....  is that the snow has been quite 
extensive in Yellowstone this year.  Those snowballs or flattened 
cylinders are either logs or larger rocks which have insulated the snow 
from melting on the extra warm, thermally heated ground.  Thus, they 
have accumulated snow over many storms giving them odd shapes.  Other 
snows have melted away.  I too, was interested when first noting them.
