Even in winter an isolated patch of snow has a special quality.

The stones tear like flesh, rather than breaking. Although what happens is violent, it is a violence that is in stone. A tear is more unnerving than a break.

I am not a performer but occasionally I deliberately work in a public context. Some sculptures need the movement of people around them to work.

At its most successful, my 'touch' looks into the heart of nature; most days I don't even get close. These things are all part of a transient process that I cannot understand unless my touch is also transient - only in this way can the cycle remain unbroken and the process be complete.

Generally in New York, people just walk over you with no problem about that. Other countries, people want to resuscitate you, like, after a bit.

People also leave presence in a place even when they are no longer there.

In contact with materials, I can see so much more with my hands than I can just with my eyes. I'm a participant, not a spectator. I see myself both as an object and a material, and the human presence is really important to the landscapes in which I work.
