The Coast Guard had to send out a helicopter to rescue a woman who got stuck while walking in the marsh on James Island Friday.

People reported hearing a woman yelling in the marsh near Sweetgrass Creek Road about 10 p.m. The area is east of Fort Johnson Road, between Charleston Harbor and Parrot Point Creek.

The Coast Guard sent a helicopter and pulled her out of the mud between 11:30 p.m. and midnight.

Rescuers found out she had been tubing with a group that got in the water about 1 p.m. near the Grice Marine Laboratory. At some point, she got separated from the group and tried to walk to shore. She got stuck, then became too tired to continue and started yelling for help.

It's not clear how long she was stuck in the mud before she was found. The Coast Guard did not identify the woman.
