Site details

The HMCS Yukon is a 366-foot, six-deck Canadian Mackenzie-class destroyer escort prepared by the San Diego Oceans Foundation and scuttled in July 2000 about two miles off Mission Beach as the centerpiece of Wreck Alley. She sank prematurely the night before her planned sinking and settled on her port side in about 100 feet of water, with the hull starting around 60 feet. Dozens of access holes were cut so a diver is never far from an exit, but the sideways orientation makes navigation disorienting and penetration is for trained wreck divers only. Heavily colonized by white Metridium anemones and strawberry anemones, it is widely considered the signature wreck dive of the US West Coast.
