I see wonderful pictures.
I watch some show on the Travel Chanel about finding treasure.
On the coast, there is a place called 'Jade Cove' and you can actually climb down the cliffs to a beach where you can find jade. It doesn't look like an easy climb nor can you take more than you can carry but it does look interesting.....

It seems the first link gives guidelines about what you can and can't take and.....we missed the turn off last time we were on the coast but we do intend to go someday....
