On Saturday, worried residents waited for permission to return to their neighborhoods to see whether their homes were still standing.
Maketa said the fire's destruction has made it difficult for his deputies to assess damage.
Deputies have said "it looks like a nuclear bomb went off in some of those areas, and you can't even recognize whether it was a house or some other kind of structure," Maketa said. "That is the level of incineration and destruction that took place in some areas."
Containment is at 45 percent, an increase from 30 percent on Friday. It's unknown what sparked the blaze, but investigators believe it was human-caused. So far, it's cost more than $3.5 million to fight.
Most mandatory evacuation orders have been lifted, as the fire zone remained at 25 square miles. Some residents have already gotten to see the damage for themselves.
Jack and Judy Roe were able to tour their neighborhood Friday, and saw to their relief that their house had been spared. Several other homes on their block, however, where destroyed.
"Our hearts were breaking for our neighbors," Judy Roe said.
Describing the scene, she said she saw charred piles of what remained of homes, with bricks the only distinguishable feature.
"But other than that, everything is black. The ground, everything is just black," she said.
Some residents were forced to evacuate so quickly they didn't have time to pack an extra change of clothes.
"This is my wardrobe," said Bob Metzger, signaling to his jeans and polo shirt. Metzger and her wife Barbara were among those who lost their house.
White House officials said Saturday that President Obama called Gov. John Hickenlooper on Friday to get an update on conditions and reinforce his commitment to help. The president also expressed his concern for the devastation and gave his condolences to families who have lost relatives.
