Thank you all for the kind sentiments. Yes, the friends are okay. Sorry, I should have included some story with the photo, especially since we got a chance to talk with them.
Hopefully investigation will bear this out, but from what I've read so far, it seems there was a secondary fire in Highland Valley the night of Monday/Tuesday. This is the area and the time the couple who lived in HV was killed. A neighbor of theirs, who ended up spending most of the night in their swimming pool, says they saw a high tension power line on the valley floor glowing red, and the Witch fire itself seemed to be miles away, and possibly moving in another direction than toward them. A few minutes after that, fires were racing up the side of the valley. They grabbed some things, got into their car in the garage, and the power went out, so they couldn't open the garage(I'm thinking they figured they didn't have time to attempt to open it manually - they came across as reasonably savvy folks). They then opted to remain in the garage as long as they could, as it had been built to be fireproof. Eventually, the smoke became so thick a flashlight beam wouldn't penetrate it at floor level, so they made a dash for their swimming pool, where they spent the next three hours, mostly huddled under a waterfall overhang to shield themselves from flying burning debris. They had told their next door neighbors - the couple who perished - to remember they had a pool, for when all else failed, and they thought of the fact they hadn't come as they languished in the pool, and hoped they had actually gotten away. They said they witnessed flames 30-40 ft high around their pool, and watched their house collapse as it burned. After the flames died down, and they had become pretty cold in the pool, they got out and hiked down the hill until they were picked up by searchers.
Our friends lived on the south side of the area where this fire occurred. Hence, they neither received any warning, and just happened to wake up when the fire was approaching. They were able to get out with the clothes on their backs, and four photo albums(their long hallway was jammed with family photos - all lost).
At least they got out alive.
