I'm surprised no one mentioned Dick Proenneke. Many years before McCandless' trip to Alaska, Dick Proenneke moved up there, built a log cabin from scratch, and lived in the middle of nowhere Alaska for 30 years by himself. There's a book and a documentary that airs on PBS every once in a while.
Alone In The Wilderness - PBS Documentary
One Man's Wilderness - Book about Dick's time in the Alaskan wilderness
Book about him here

Have you read One Man's Wilderness or watched Alone in the Wilderness ?
One Man's Wilderness by Sam Keith and Richard Proenneke is an absolute classic.
Indian Creek Chronicles by Pete Fromm is another of my favorites.
For inspiration check out the film series Alone in the Wilderness along with the accompanying book. Also, one of the top videos in r/ArtisanVideos right now is a group of Finnish builders making a cabin.
I did enjoy the PBS documentary. If you like, you can read the book written from his journals - One Man's Wilderness or another which is mostly his actual journals collected into a book More Readings From One Man's Wilderness.
The first book is a retelling of his life from the journals. However, Dick stated that if his journals were ever published, he wanted them in his own words (which the original book didn't) so the second book was put out.
Of course, if you don't want to drop any money or support the author, and don't mind reading from a PDF, the second book More Readings is available on the National Park Service website at http://www.cr.nps.gov/history/online_books/lacl/proenneke.pdf
And as a final esoteric entry, if you read his books and enjoyed all the sourdough cooking he did, you can purchase the actual sourdough starter he used at http://alaskasgoldenspoon.com/page2.cfm?recordid=45
Lastly I don't think it's fair or reasonable to compare Dick with Les or Bear as they have different goals. I don't think Dick's intent was to survive under difficult conditions. He like the Alaskan wilderness and wanted to live a comfortable life using his own skills to provide. He certainly didn't live off the land as his diet was primarily supplied by groceries brought in periodically by air. He did supplement his food with items he hunted (only legally during hunting season) and foraged food. But his main diet was sourdough products like pancakes and biscuits and beans.

I did not call her a mooch. I said she is mooching off her parents with regard to the construction location of her crap shack.
This may be shocking, but some of my experience comes from real life. For example, my uncle has built such a cabin and I have spent many a happy night in it. However, Dick Proenneke's cabin in Alaska would be an example of such craftsmanship. He documented the construction of his cabin in journal entries and with his video camera. He lived in this cabin year round for more than 30 years. I would highly recommend the book One Man's Wilderness
