These are sand sculptures from the Port Aransas, TX Gulf Coast SandFest.  A competition is held every year there in late April.. 

There are only two components to these sculptures;  Sand and water.  Wet sand is compacted in layers in wood forms.  After compaction the forms are removed and the delicate art of sculpture begins.
