“Essentially, around here the cliffs and landscape act more like concrete and so when it rains, everything pours off pretty quickly,” says Alyssa Baltrus, Zion National Park Chief of Interpretation and Visitor Services. If you’re planning on taking a trip to Zion National Park or one of Utah’s canyons such as Buckskin Gulch, one of the biggest dangers you’ll face is a flash flood. Although there are flash-flood warnings from the National Weather Service on the Zion National Park website, it can never be known for sure whether or not flash floods will occur.
