That's very interesting and worth some further looking into. I wonder if any of the gold was ever recovered?
Starting in 1988 / 89 and then again in 2014, no doubt the major portion has been recovered, and what a tale that is as well. The underwater recovery at about one and a half miles down required the invention of "Nemo" a tethered six ton robotic device that was far beyond simply "State of the Art" at that time and is the precursor of the more advanced systems in use today. Certainly, a whole 'nother twist in the tale of this incredible series of events with more twists and turns than you could possibly ever imagine in your wildest dreams!!!
Oh yes, and the treasure is now worth in the hundreds of millions of dollars from various auctions and private sales. Some of it can even still be found on eBay and the like in what are typically the smaller increments of original 49er gold rush dust and small nuggets. The coins demand significant premiums as they are undoubtedly the best preserved and highest mint state condition of any from that era, while the ingots fetch staggering sums when they come up for resale!
Books, videos and the internet will go far to illuminate the details of this unbelievable tale for you!
