I spent 2 summers working for the Park Service.
The bonus is that you live in a gorgeous area where thousands of people go on vacation. I hiked all the time and got to help out with a few SAR's. The pay is all right and you get paid holidays and vacation pay.
The downside is that your working for the Govt. You'd think most of the employees would be super gung ho outdoors people, but for a lot of them it is just a job. Lots of politics going on if you like it or not.
And a far as using survival skills in the backcountry, forget it. Most parks don't allow open fires and cutting trees and such will get you a fine.
Take my advice, get a job with the Forest Service instead.
