Clackamas firefighters continue to work shifts at the wildfire that has essentially destroyed the Northern California city of Paradise.

Clackamas Fire's Strike Team is working with bulldozer teams to reinforce fire lines, prep and protect vital structures and mop up areas that have burned.

"These are incredibly long days and hard work but our crews have risen to the occasion to help those in need," said Clackamas Fire spokesman Brandon Paxton. "We are all very proud of their efforts. No word on how much longer they will be there."

The fire has destroyed more than 17,000 structures, including more than 12,600 homes, according a Nov. 20 incident report. Of the 79 dead, 64 have been identified. The Butte County Sheriff's Office said 699 people are missing.
