Well, if you consider shipwrecks, buried forests, and some previously covered geologic formations to be treasure, that is. Due to the action of some powerful storms around the northern tip of the Oregon coast, parts of the shore underwent massive erosion, revealing the previously entombed oddities. Indeed, you never know what large storms might turn up along the shore; mastodon teeth have been found along one New Jersey beach as storms sometimes cast remains from a near-shore deposit onto the sand.
