Canadian authorities and search-and-rescue teams are searching for a 62-year-old Australian woman, Denise Ann Williams, who has been missing for nearly two weeks in Cape Breton Highlands National Park (a coastal wilderness park on Cape Breton Island, Nova Scotia, in eastern Canada). Williams was last heard from on 15 April, when she told family she was heading to the area; her rental car has remained stationary at the trailhead of the Acadian trail — an 8.4km moderate hiking loop — since that time. The search involves air and ground teams navigating challenging terrain with steep inclines, lingering snow, and wildlife including bears emerging from hibernation, with overnight temperatures dropping as low as -5°C.
