<p>A team of divers has discovered what appears to be the oldest shipwreck ever found in Alaska waters, the remains of a three-masted Russian sailing freighter called the Kadi'ak, which sank off Kodiak Island in March 1860.</p>
<p>The searchers, led by Bradley Stevens, a scientist with the National Marine Fisheries Service, located a cannon, an anchor and what they believe to be copper sheeting in an underwater sand channel off Spruce Island, said Steve Lloyd, one of the divers.</p>
