we don't have the sheer volume of wrecks you have, so generally speaking our wreckers leave things... its taken years of peer pressure (starting back in the early 90's) to convince peeps to not salvage. having been one of the first recreational divers on our deep wrecks, i can quite honestly say "the reason some of these things are here for us to look at today is because I personally chose to take pictures instead of souvenirs" i actively left them for the 'future generations'.

that wreck is in 90' of water, in lake washington, a pleasant little scooter ride from shore. You'll notice that one of the portholes is loose but has still been left there, along with her little two bladed prop
