Are you a sculptor, or are you a photographer?
Both, but I'm primarily a sculptor. With very rare exceptions, I sculpt without giving any thought to photography until after the the sculpture is done. In most cases, I take photos to simply document the work, but I sometimes decide to create an image that can stand as an artwork on its own.

What happens to the sculptures when you leave?
In general, my sculptures are dismantled by the forces of nature. If I make something like a tall rock tower that could be dangerous, I take it down myself.

Do you use glue, rods, or photographic tricks?
I generally use what nature gives me ready-made at the site. On occasion, I have used sap and spit as glue. I sometimes adjust the brightness, contrast, hue, and saturation of my photos to make them more closely match my memory of the moment.

How do you make sand globes?
I've recenty revealed the "secret of sand globes." I toss the globe in the air constantly, in order to minimize gravitational forces and evenly distribute the water inside, adding wet sand intermittently to grow the globe. The intermolecular force that attracts water molecules to each other is the "glue" that holds the globe together. (See this video of water in outer space to get an idea of the strength of attraction that water has to itself.) When the globe is "fully grown," I add dry sand to harden it. I've developed my method over a period of years, but I can teach it to you in about five minutes if you come to the beach with me.
