There is a pretty darn good school to the south of you http://www.uidaho.edu/cnr/majors-and-options If you want to work outside, I would suggest getting a temporary posisition in the summer working outside for either WCC or any agency and going to school in the off season.You need experience and schooling to really advance in pay.
If you don't have a bachelor's, that would be my advice, pursue your education.
