I have spent the last three summers working for the National Park Service as an Interpretive Ranger. I started working on my retirement plan during the last two years of my employment as a history teacher in the Arizona public schools. Through the Teacher- Ranger- Teacher program offered by the NPS, I got a chance to work during the summer break as an Interp Ranger at two different parks. After my retirement, and with that experience, I was hired by the NPS as a full-time seasonal Interp at Mesa Verde. Full time seasonals typically work anywhere from three to six months.
I live in the park in my Argosy and love this job. This may be an option for some. The NPS has three classifications of Rangers: Interp- leads tours and man the visitor centers. Experience in History, Biology, Geology, Anthropology, depending on the park, is helpful. Protection- Law Enforcement requires a Park Service Type II LE Certificate. Visitor Use- Collects fees and mans the entrance kiosks. Also sells merchandise in the visitor centers. Experience in finance, retail sales or high volume customer contact is helpful. Other jobs include maintenance, health techs, equipment operators and lifeguards.
Other Park jobs are in hospitality. The NPS has concessionaires who run the lodges and restaurants. Employees work for the concessionaire. One of the big ones is AAMARK. There are others, so check out the park that interests you.
There is a very large sub-culture of people who work one park in the summer, and then go south and work another park in the winter.
It's not for everyone, but if you love people and the challenge of mastering the information needed for the job, its alot of fun.
Oh, and did I mention that you get to live in your AS in places others can only dream about?
