DARRINGTON, Wash. -- Two hikers from Wisconsin are stuck on a narrow mountain ledge in Washington State's North Cascade Mountains and will spend another night waiting for rescuers.

Snohomish County dispatch received a cell phone call from two hikers advising they were stranded on Wednesday. Snohomish Dispatch determined this was in Skagit County and the call was transferred.

Skagit County Sher iff's deputies and search and rescue personnel contacted the stranded hikers via cell phone. They have been identified as Matthew Edwards, 33, and Robin Gibson, 27.

The two hikers became stranded on an 18-inch ledge and are unable to climb up or down. Authorities said the Wisconsin couple has made their way to a safer spot to wait for rescuers.

Authorities said rescuers are close to the two hikers but were unable to get them off the mountain Thursday. They will resume their rescue Friday and said rescuers know the location of the couple and are about 1,000 feet below them.

An earlier attempt to rescue the hikers by a Navy helicopter failed as the helicopter had to turn back due to low visibility and inclement weather.

The U.S. Navy said it has their helicopter on stand by in case of a break in the weather.
