Yellowstone National Park has set a record in 2015 with its total number of visitors surpassing 4 million.
The Cody Enterprise reports that the National Park Service says the record total of 4,097,710 visitors is up more than 16 percent from 2014, putting last year at the highest visitation year on record.
The National Park Service attributes the record year to lower gas prices as well as its public awareness campaign, marketing and tourism promotions by the states of Montana and Wyoming.
Yellowstone National Park Superintendent Dan Wenk says the park is making improvements to be able to accommodate the growing number of visitors.
Congress approved increased funding for national parks this year.
