Hamilton County officials responded to a fall on Signal Mountain Saturday afternoon.

Crews responded to the 900 block of Falling Water Trail just before 1 p.m. where an 18-year-old fell.

Hamilton County EMS spokesperson Amy Maxwell says Shelby Mudd slipped on a rock and landed on her foot wrong. It took emergency crews about 20 minutes to get to her.

Crews had to use a rescue device, called a Stokes Basket to get her out, but because the area was hilly and rocky terrain, and they wanted to avoid shaking Mudd's injured ankle, rescue efforts were slow going.

Mudd's friends say the fall made them realize they need to stay on the trail and be more careful.

"I like froze, there's nothing I could do, because my friend was falling down a cliff and rolling, I'm definitely going to be a lot more careful now." 

The group was not on a marked trail.

Walden's Ridge Emergency Services, Signal Mountain Fire Department, Lone Oak VFD, TN State Park and Chattanooga-Hamilton County Rescue were on the scene.
