A partial collapse at an ice cave in Washington state may have trapped several hikers, local media reported on Monday, and authorities were trying to determine if anyone was inside at the time or injured.


In a brief statement on Twitter, the Snohomish County Sheriff's Office released limited details on the collapse at the Big Four Ice Caves near Granite Falls. Officials could not be reached for additional detail.

Sheriff's Office spokeswoman Shari Ireton told local broadcaster KOMO that several people called to report the collapse, saying that several hikers may be trapped inside the cave and hurt.

The caves are home to a popular hiking trail and are part of the Mt. Baker-Snoqualmie National Forest, according to the U.S. Forest Service.

Further details were not immediately available.
