Page "Student Conservation Association" Paragraph 2

Every summer, over 600 young people aged 15 + are placed into crews of 6 or 8 in national parks, national wilderness areas, national monuments, Bureau of Land Management-controlled lands, even military ranges, as well as a variety of other federally controlled lands throughout the United States.

The crews are divided into frontcountry and backcountry crews, with frontcountry crews being based within one mile of a road and most likely having easier access to showers, stores, and park rangers.

Backcountry crews are usually more isolated and provide a completely different experience.
