Undaunted Courage is a great book, my wife and I visited Fort Clastop on the way to visit the goonies house in Astoria, we stopped there because I had read that book. I am really glad we did because it was really fun and super informative. They have a cool museum and a replica of the small fort they built. It was a rainy and cold day and we got a great tour from the ranger who was bored. He taught us how to make a window with a deer hide. It would be tough to survive but these guys were pros and did an amazing job on that journey. The Oregon coast in winter is no joke, that was real wilderness and still is in some ways. I certainly enjoyed it much more than the goonie house... my wife, well she is a goonie but she enjoyed the fort also. Wine, micro beer, sausage and cheese plus camping along the west coast on a road trip from Yosimite to Astoria is a great way make or break a realtionship. It made ours.
