Norfolk Rocks has made its mark across the pond after a painted pebble was discovered in Oklahoma.
Members of the stone-sharing group are encouraged to decorate small rocks and hide them around the region, leaving instructions on the back with details of the Facebook group where they can post photos of their discoveries.
Finders are then invited to re-hide the rock if they so wish.
The Facebook group has over 34,500 members and it was here that Karen Downes posted an image of herself with a colourful stone in America. She found it outside the COX Conference Centre in downtown Tulsa.
'EEEK! Look what I found in TULSA USA this weekend!!!' she wrote on the page.
Soon after rock creator Lisa Hutchinson replied, revealing that it was in fact one of her daughter Tia's painted rocks.
The Hutchinson family are thrilled that one of 'Tia's treasures' made it all the way to Tulsa, Oklahoma, and Karen, originally from Sheffield, is pleased to have discovered the community of Norfolk Rocks too.
She said: 'I picked it up and saw the information on the back. My friend said that she had heard of this before and knew of the Facebook page where I could post my photo.
'I thought it was amazing that it had travelled all the way to the USA. I travel a lot and I plan to take it with me to my next venture and let some lucky person find it abroad like I did too,' she added.
Lisa, who is from Gorleston, commented: 'I'm slightly jealous that a rock will travel further than I ever will,' although she is nonetheless amazed that the glow-in-the-dark painted rock was picked up abroad.
The Hutchinson family are now busy painting their next batch of rocks and are hoping to host a Norfolk Rocks glow-in-the-dark Halloween trail very soon.
Let's see how far their next creation can get...
