X MARKS the spot ... or maybe not.
Well, at least that's the case for a 100-year-old time capsule at Conondale State School.
Old and new students have been scratching their heads as to the whereabouts of the capsule, which was buried to mark the opening of the school in 1912.
The school will celebrate its centenary in September and there are big plans to dig the capsule out of the ground and reveal what is 8 inside.
But with no map or records of where the capsule was buried, principal Mark Winrow said it could be anywhere.
"We have several possibilities at this stage, but we really have no idea," Mr Winrow said.
"No one knows what it was made of and it could even be buried under a new school building."
It was believed a time capsule was buried every 25 years, which would mean four capsules have been hidden somewhere in the school grounds.
A metal detector has been hired to help with the hunt, but Mr Winrow said it could come down to digging up the school yard.
"We obviously want to keep the grounds looking good for the celebration, but it is pretty important that we find at least one of the capsules," he said.
Some ex-students recall seeing a capsule being buried.
"Some say it is here and there, and other people say the opposite, so we would rather be certain before we start digging," Mr Winrow said.
The school was seeking past students with information on the capsules to contact the school as soon as possible.
