Biography of Gary Snyder?

Hi...

Can anyone tell me if there is a biography of Gary
Snyder in the works now, while he is still with us?

Snyder is recognized as an important 20th century
American poet, as well as an environmental activist who
has been prominent, and a person who has made
contributions to anthropology and to closing the gap in
understanding between the cultures of the West and
Asia.

I'm aware of the semi-biographic study of Snyder's work
written 25 years ago or so by Bob Steuding, and of the
fine collection of impressions and reminiscences
written by Snyder's friends and colleagues, edited by
Jon Halper 10 or 12 years ago. These should make a
fine basis for someone to begin work on a more probing
bio.

Is anyone at work on such?
