Medallion Hunt

Clue #1

Let's search this land between the rivers, as close to an island as we can deliver. The medallion is hidden, for that we're quite sure. 

No need to dig, damage or destroy the public property, rest assured. As you join with the Kaiaulu, we wish you Pomaika`i ia oe, if you find the waiwai i hao`ia, redeem your prize!

Clue #2

You know the perimeters, north east south and west, but to be in Hawaii would certainly be best! 

We'll make do, right here, in our own paradise, we have land and water - it does suffice. 

Don't go close to the rivers, they're not in the limits. Look further inland, but only by minutes.
