PARADISE, Calif. — In northern California, apocalyptic images are revealing entire lives incinerated in a matter of minutes. Four days have passed since the raging Camp Fire first ripped through the retirement community of Paradise and beyond, burning at a rate of 30 football fields per minute and hot enough to melt car parts. Downed PG&E power lines, combined with high winds, are believed to have sparked the fire.

One mobile home park was obliterated by the wildfire. Crews are now searching through tons of rubble and bringing in cadaver dogs. With more than 200 people still unaccounted for, families who are desperate for answers are posting pictures of their loved ones online and on message boards at shelters.

"In some cases the remains we are recovering are nothing but ash and bone," said Kory Honea, the Butte County sheriff.

Darrell Wilken, a registered nurse, is thankful to be alive. He drove right through the towering inferno with three of his elderly patients as they fled Paradise.

"Everywhere the cars were on fire and I didn't see anybody walking and all I could think of is there were people in those cars," Wilken said.

It took more than three hours to get through hell.

"I'm still shaking. Every time I talk about it," he said.
