JACKSON, Wyo. (AP) — The number of visitors to Grand Teton National Park in June was down 10 percent from the same month just last year — a brief swoon in a season that's seen brisk visitor numbers.

Some 570,000 people visited the park in June. Last year, June visits set a record for the month, and all-time high numbers were seen in April and May of this year.

More than 1 million visitors have entered the park so far this year. July and August are normally the park's busiest months.
