sand dune is growing

We've removed all of the sand from where the kitchen addition was dug out.  Martin then wanted the dirt to be leveled, so we have spent two days digging the high spots.  We have about a quarter of the area left to dig to make the whole space under the house level.  All of the sand and soil has been added to this pile.  We are running out of room and we aren't sure what we are going to do with the sand/soil from digging out the basement.

This is the same pile of which I put pictures in under the post "giant sandbox". It grew a little.
