ZION NATIONAL PARK » A wildfire has burned about 20 acres in Zion National Park and forced the closure of one of its trails.

The fire was discovered Tuesday in the northern portion of the park near Lava Point. To protect visitors, park officials temporarily closed the West Rim Trail from Lava Point to Potato Hollow.

Fire officials plan to keep it confined to the east side of the trail and allow it to burn into an area that burned last fall.

The fire is being managed by the National Park Service, the Bureau of Land Management and state officials.
