PHOENIX -- The Grand Canyon National Park had almost 4.5 million visitors last year and those visitors won't have to look hard to see the impact of the sequester.
Maureen Oltrogee with the National Park Service said visitors can expect to see closed trails and dirtier bathrooms and campgrounds.
"Obviously the busier the park gets and the less staff we have, the more chances of longer lines getting into the park."
The canyon is getting into the busy season and, for now, won't be able to hire up the extra seasonal help.
"We won't have the extra staff that we need as we're gearing up at the entrance stations," said Oltrogee. "If we can't open up all of the gates and stacking lanes, that could delay people getting into the park."
Winter could add to the challenge. A major snowstorm could mean it will take longer to get the roads cleared.
A Michigan State University study said Grand Canyon visitors spent almost $500 million in 2011.
