Rescue crews have posted three more videos — shot from helicopter on Dec. 28 over B.C.'s Grouse Mountain and Lynn Valley — in an effort to find missing British tourist Tom Billings.
The move comes two days after three similar videos of Vancouver's North Shore mountains were released in hope that the public might notice something that will aid the search.

Billings, 22, went missing while visiting Vancouver at the end of November. He had been on an eight-week tour of North America. He was last seen on Nov. 25 in the 1400 block of East Broadway in Vancouver.
He was reported missing when he failed to follow his itinerary in and around Vancouver and did not return to the U.K. as planned on Dec. 7.
'I don't think the closure is likely to be very pleasant, but all the time you don't have certainty, thoughts go round in your mind.' - Martin Billings
Family seeks closure
This latest search and rescue effort is being funded by the Billings family.
It is thought Billings may have gone hiking on the North Shore, something he had previously discussed.
Since the first set of videos was released, North Shore Rescue says it has received a lot of assistance from the public, including a credible tip from two hikers who may have seen Tom on Nov. 25 in the area of Lynn Headwaters.
His father Martin Billings, who flew to Vancouver earlier this month to appeal for the public's help, spoke to CBC News via Skype on Boxing Day.
He said if his son was on the North Shore, the possibility of him being alive was very remote.
"In this situation, you just feel the need to get some sort of closure. I don't think the closure is likely to be very pleasant, but all the time you don't have certainty, thoughts go round in your mind," he said.
Martin said the Christmas season has felt more "poignant" for him and his family without Tom.
"That's going on for everybody else out there, but for us time seems to be standing still," he said.
"We'd love it if he knocked on the door in five minutes' time and said 'Oh hi Mum, hi Dad, I've just been doing something and here I am', but I don't think that's likely to happen."
