Zion National Park marks its 100th anniversary later this month.
The July 31 event will include speakers, dedication of the rehabilitated Grotto Museum building, Paiute dancers and an evening chamber music concert.
The ceremony begins at 9:30 a.m. Entrance into the park will be free that day.
The park was established as Mukuntuweap National Monument by President William Taft on July 31, 1909. It was rededicated as Zion National Park a decade later.

A wildfire burning in Zion Natural Park that forced the closure of a hiking trail has spread over 450 acres, but was reported to be 25 percent contained Wednesday.
The lightning-sparked Horse fire was discovered on July 7 and is located about 1½ miles southeast of Lava Point, in the northern part of the park.
On Wednesday, park officials said the northern part of the fire, which is most worrisome to fire officials, was slowed by a lack of fuel when it reached an area that was burned last fall.
The southern and eastern parts of the fire continued moderate growth Tuesday. The West Rim Trail from Lava Point to Potato Hollow was temporarily closed to protect visitors.
Smoke from the fire may settle into canyons at night, especially Zion Canyon, but canyon winds should blow it away by mid-morning, park fire spokesman David Eaker said in a news release.
