“Helicopters and drones continued to use infrared devices during the search however, all were negative for any signs of Sands,” the department’s statement said.
Sands, 65, was reported missing on January 13 while hiking.
Search and rescue crews began looking for him on the highest peak in the San Gabriel Mountains, about 65km northeast of downtown Los Angeles.
Storms have coated the mountain with heavy snow and ice, and searches have been thwarted by the threat of avalanches and foul weather, including powerful winds.
Authorities describe mountain conditions as extremely dangerous. Two hikers have died in recent weeks. One fell at least 150m down an icy slope.
Sands starred opposite Helena Bonham Carter in the 1985 British romance from director James Ivory, “A Room With a View”.
He also had major roles in in 1989′s “Warlock”, 1990′s “Arachnophobia”, 1991′s “Naked Lunch”, 1993′s “Boxing Helena”, and 1995′s “Leaving Las Vegas”.
Sands has worked consistently in the decades since with smaller roles in film and television.
