SALT LAKE CITY (AP) — A trail at Utah's Zion National Park remains closed after a second rock fall occurred in the area in two days.

Park spokeswoman Aly Baltrus says the Hidden Canyon Trial will stay shuttered on the July 4 holiday and at least through the following day until a hazard geologist can examine the area and the trail can be cleared.

A rock fall first occurred Monday afternoon in a 45-foot section of the strenuous trail where hikers must hold onto chains.

A second rock fall occurred Tuesday.

No injuries occurred in either rock fall.
