Yellowstone National Park officials are crediting relatively low gas prices and the park's affordability after a record number of people visited in July. America's first national park hosted more than 900,500 people last month, up more than 11% from July 2008 and 6% from the previous monthly record set in July 1995.
The park is on pace to set a visitor record for the year. More than 1.9 million people have been to Yellowstone through July, up 100,000 from the previous seven-month high in 2007. July's numbers build on June's record for that month of about 644,000 visitors. July is typically the park's peak visitation month, followed by August, June, September, and May.
