The Golden Tortoise Traditional Cache

This golden artifiact will be found in a silver box.  I'm not sure but it could be from King Tut. 

You are looking for a silver box in a big split soft oak tree.  The tree is in driveway into a farm but it is not necessary to open or go beyond the gate.  The cache is probably private property but this place was my grandparent's farm and we still own it - so permission granted.
