Literature about a natural place?

What literature, whether fiction or non-fiction, features a non-fictional landscape prominently? I am looking for writings where the natural world is important to the work and vividly described.

Some examples:

Thoughts from Walden Pond
Blood Meridian
Little House on the Prairie
The Painter
Tom Sawyer
Shadow Country
Cannery Row
Suttree

Island of the Blue Dolphins might fit the bill.

My First Summer in the Sierra (and other writing by John Muir) springs to mind.

The Worst Journey in the World is also a favourite - an incredible story.

The Lacuna by Barbara Kingsolver -- and about a lot more things like all her novels.

The list of books that would fit is almost endless.
A few that spring to my mind:
Tarka the otter
Ring of bright water
I bought a mountain
Independent people
The man who planted trees
La gloire de mon père (and the rest of Pagnol's books)
Jack London's Alaska books
Our village (Miss Mitford)

The tagmashes http://www.librarything.com/tag/fiction,+nature and http://www.librarything.com/tag/nature,+non-fiction have a lot more

I second Independent People.
Landscape: The Return of the Native (moors) and The Woodlanders (woods or maybe just copses) by Hardy.

>7 MrAndrew: Yes. Actually any Hardy, and almost any D.H. Lawrence, would fit.

I'm currently reading My Antonia, which is like Little House on the Prairie for grown-ups.

The Good Earth is all about the importance of the land (albeit as property).

>8 thorold: Hardy is handy that way.

Just waiting for a "light-hearted and optimistic worldview" thread so i can suggest Hardy again.

>5 Limelite:
I second anything by Barbara Kingsolver but especially Prodigal Summer and Flight Behavior

The Natural History of Selborne by Rev Gilbert White

James Fennimore Cooper's Leatherstocking series captured the primeval forest for me. Wallace Stegner's books had a sense of space - the West - as did those of Edward Abbey. John McPhee could write with a sense of space, especially his geology series.

Driving Over Lemons: An Optimist in Andalucia by Chris Stewart

I have read several on the original list and loved them. Here are some others.

I'll add Andy Russell's Campfire Stories about mountain wild life and scenery, very vivid.
