The California wildfires have raged for more than a week, killing 40 people, destroying thousands of structures, and reducing hundreds of thousands of acres to smoldering rubble. Encouraged by gusty winds, more than 20 separate blazes have wiped businesses, homes, wineries, and entire neighborhoods out of existence.

While the worst damage has come in the wine country north of the San Francisco Bay Area, the devastation is hardly limited to this area. The Canyon 2 Fire in Anaheim — marked by an ominous glow around Disneyland — burned at least a dozen structures in Orange County and forced thousands from their homes.

As officials comb the blackened ruins of the hardest-hit areas of Northern California, they face a new grim reality: "We may never get truly confirmative identification on ashes," Sonoma County Sheriff Rob Giordano said during a press conference. "When you're cremated, you can't get an ID."

Officials warn that recovery will be extensive and costly. And while the region's wine business could take years to recuperate, the personal toll is what's truly immeasurable.

"We're going to be a long time recovering from this incident," Santa Rosa Mayor Chris Coursey said. "[We've] suffered a serious blow."

Below, witness the unfathomable wrath of the California wildfires, one of the most devastating series of blazes to strike in modern history.
