Over 100 people were rescued by helicopter after being trapped by flash floods near the Grand Canyon, but one hiker, Chenoa Nickerson, remains missing.

Nickerson, 33, was last seen in the remote Havasupai Indian Reservation in Arizona, where she was hiking with her husband when the floods hit.

Her husband was rescued, but search efforts to find Nickerson have so far been unsuccessful.

The Arizona National Guard has evacuated tourists and tribal members, while search teams continue to look for Nickerson.

Governor Katie Hobbs assured that all efforts are being made to ensure safety and find the missing hiker, the U.S. Sun has reported.

Nickerson’s family has expressed gratitude for the rescue efforts and is hoping for her safe return.
