Dramatic video captured a terrifyingly close call in Utah when several boulders came crashing down just feet away from two swimmers cooling off at Lower Calf Creek Falls.

The popular waterfall in Grand Staircase-Escalante National Monument has rocks that hang over the pool of water below. When rocks come loose, they can fall far away from the cliff wall directly in the water.

"Outdoor recreation can be inherently unpredictable. This is not a backyard swimming pool, but rather a remote and natural place. Lower Calf Creek Falls is a world-famous destination, and we want to make sure everyone understands the risks when they visit," National Monument Manager Ade Nelson said.

Fortunately, the two escaped uninjured.


The Bureau of Land Management said that it will assess Lower Calf Creek Falls and determine how to reduce the risk of further rockfalls.

The waterfall is in a remote area of south-central Utah and is the scenic destination of a 6-mile hiking trail. Hikers are rewarded with views of the 126-foot waterfall, although officials warn of the hot conditions during the summer months.

Rockfalls can be unpredictable, so visitors are encouraged to use caution while visiting Lower Calf Creek Falls.
