Clue 1:

29 May

In a patch of green where townsfolk roam,
Stands a tribute carved in local stone.
A miner once rested here, boots full of clay,
After finding a fortune that led the way.
He sparked a rush with a single claim,
And carved his name in Zeehan’s fame.
He struck the first of silver's shine,
A glint that marked the mining line.

When you find this place, ask yourself:
Before the miners cleared the land,
What ancient giant used to stand?
