A US woman has been talking about being rescued after becoming lost near the Grand Canyon.

Texan student Amber Vanhecke, 24, told US broadcaster ABC she had been stranded for five days in a remote part of Arizona.

She was visiting the area to hike and got lost when her car ran out of fuel.

When a rescue helicopter spotted her abandoned car last Friday, they found a note inside saying she had gone to try and get a mobile phone signal.

Shortly afterwards she was seen "frantically waving" to get their attention.

The Arizona Department of Public Safety (DPS) said in a statement that she had alerted them with an emergency call but the line had dropped before her location was confirmed.

She was treated at the scene for exposure and then transported to hospital.

A DPS paramedic described the woman as "smart and prepared".

"She had food and water in her vehicle for the trip," Edgar Bissonette told CBS. "Even though she was down to her last bit of water, it kept her going. When she left the vehicle, she left notes so we knew where to find her. She did everything right."
