If you've ever come across a tree that you've lived with for many years and then one day it's blown over, there's incredible shock and violence about that.

I can't edit the materials I work with. My remit is to work with nature as a whole.

A lot of my work is like picking potatoes; you have to get into the rhythm of it. It is different than patience. It is not thinking. It is working with the rhythm.

Photography is a way of putting distance between myself and the work which sometimes helps me to see more clearly what it is that I have made.

When it does get below freezing and there is - it's cold enough for ice to form, then that changes the whole landscape, and it makes the landscape a different landscape to the one that I worked with previously. And I want to understand that. But the big tension of the ice works is that they're often made when it's cold enough to freeze one piece of ice to another.

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.

If you repeat something, it can become pointless. Some things can repeat and be endlessly fascinating.
