Yellowstone and Grand Teton national parks and their gateway communities received more than $750 million in tourist spending that supported more than 11,000 jobs in 2010, according to a new report from the National Park Service. The study found that national park visitors nationwide pumped more than $31 billion into local economies and supported 258,000 jobs in 2010, offering a counterpoint to energy industry advocates who want fewer limits on federal lands managed by Salazar, including environmentally sensitive areas near parks.
