Isabel and Alex happily stomp through the deep moat I have dug around a pyramidal sandcastle. The sand from the moat is used to create the mound of sand. Layers of the mound are drenched in water and packed down by hand.
I left one side of the design "flat" with beach so that I would have access to the top of the mound where the towers are just beginning to be poured. Steps leading into the moat have not been carved yet.
