Footage by Douglas Thron. Maybe turn the sound off.

Hovering above the charred lawns, burnt-out cars and smoldering foundations where family homes stood days earlier, a drone captures the eerie sight of a lone USPS mail carrier filling boxes with the day’s post, to which no homes remain.

The drone footage, recorded by aerial real-estate photographer Douglas Thron, gives a surreal glimpse into the utter devastation left in the wake of Sonoma, Napa and Mendocino County’s recent string of wildfires.

The footage above shows the remains of Santa Rosa’s Coffey Park, where SF Gate reports a sprawling neighborhood full of colorful single-family homes once stood in place of the now barren cul-de-sacs.

The Washington Post reported yesterday that 31 people have officially been killed between the numerous fires plaguing California’s wine country, making it the deadliest wildfire incident in state history. California’s former deadliest wildfire came in 1933, when 29 L.A. firefighters died battling a blaze in Griffith Park. The death toll for the Sonoma, Napa and Mendocino County wildfires are expected to rise again today.

A longer video below shows more of the surreal destruction left by what may be remembered as one of the most tragic natural disasters California history.
