A woman fell down a toilet as she tried to retrieve her phone.
The unnamed woman had been using her phone when it suddenly fell into a vault toilet at the top of Mount Walker in Washington state, according to reports from the Kitsap Sun newspaper.
A vault toilet is a non-flush loo that is constructed with a vault or sealed container that is buried deep in the ground.
Brinnon Fire Department Chief Tim Manly explained that the woman, who is in her 40s, managed to take the toilet seat off and used dog leads in an attempt to reach the device.
When this failed, she used the leads to tie herself to the toilet as she reached for it but ended up falling in headfirst.
Manly said: "They didn't work very well and in she went."
The woman spent 15 minutes attempting to get out but called the emergency services after being reunited with her phone down the toilet.
The Brinnon Fire Department confirmed that she was uninjured but had been "strongly encouraged to seek medical attention after being exposed to human waste".
