As with all my work, whether it's a leaf on a rock or ice on a rock, I'm trying to get beneath the surface appearance of things. Working the surface of a stone is an attempt to understand the internal energy of the stone.

I want to get under the surface. When I work with a leaf, rock, stick, it is not just that material in itself, it is an opening into the processes of life within and around it. When I leave it, these processes continue.

Ephemeral work made outside, for and about a day, lies at the core of my art and its making must be kept private.

Occasionally I have come across a last patch of snow on top of a mountain in late May or June. There's something very powerful about finding snow in summer.

Winter makes a bridge between one year and another and, in this case, one century and the next.

A snowball is simple, direct and familiar to most of us. I use this simplicity as a container for feelings and ideas that function on many levels.

We often forget that we are nature.
