Great Basin National Park, the only national park wholly within the borders of Nevada, occupies 77,180 acres and contains 42 known caves. About 90,000 people visit the park each year. It has 25 permanent staff who, with the seasonal staff, collect $280,00 in fees a year, mostly for the 2,400 cave tours. The park also has about 80 volunteers who contribute 9,400 hours of work a year.
