I'm not going to say which lake cause they kinda get crossed when you take drift wood so you could imagine what happens when you remove the find of the century... or a rock for that matter...., this rock has been eye dated to be at least a million-billion-trillion-quadrillion years old, or at least as old as the first big foot sighting in the year 1 A.D. I don't have equipment to carbon date this but I'm assuming since the lake is near a once active volcano... and possibly could be active again, it's probably lava rock of some sort or perhaps something that got blasted the last time there was an eruption..., also it smells like sulfur, or did at first when I found, it I'm not sure now..., it's been in a container in the garage for some time now... along with my looks-like-a dino egg rock that finally, accidentally, broke on me to prove it was just an ordinary egg shaped rock :(::::
