David Rains Wallace is highly regarded for his writing about the natural world, pretty much anywhere IN the world.
His book about the Klamath Mountains, The Klamath Knot, was recognized as one of the 100 best non-fiction books of the 20th century.
And he's written plenty since that time, including many of the essays collected for Articulate Earth: Adventures in Eco-Criticism. We could talk for days about the places he's visited and what he's written about them; we have to settle for a January 2015 interview that we revisit here.
