SPRINGDALE, UT – On September 15 at 1 pm, a rockfall was reported at the start of the Narrows, about 250 meters past the end of Riverside Walk. The rockfall originated from the Navajo Sandstone. Several cobble-sized blocks came down into the river as well as a plume of sand and dust, indicating that the source came from up high and likely hit a ledge on its way down. The source area may have come down from as high 146 meters. One of the cobble sized blocks hit a visitor. Medics and a search and rescue team were dispatched to the area. The patient, a young adult female, was transported to the hospital. No additional injuries were reported.

The Narrows and Riverside Walk were closed after the rockfall. Immediately after a rockfall occurs, there is an elevated rockfall risk of additional material coming down. Park staff are continuing to assess the area. The Narrows and Riverside Walk will remain closed today, they will re-open tomorrow morning.
