"This is very sad to see".
Some survivors resent that Mr Trump tweeted two days after the disaster to blame poor forest mismanagement. Jerry Brown and Gov. -elect Gavin Newsom welcomed Trump's visit, declaring it's time "to pull together for the people of California". Brown said the federal government was doing what it needed to do, including supporting first responders and helping with clean-up and search for victims.
The disaster already ranks among the deadliest U.S. wildfires since the turn of the last century. Eighty-seven people perished in the Big Burn firestorm that swept the Northern Rockies in August 1910. Minnesota's Cloquet Fire in October 1918 killed 450 people.
But during his visit to Paradise, Calif., on Saturday morning, Trump made similar comments about forest management. "We want to thank you all for coming and being here, and showing, because I think people have to see this, really, to understand it", said the President.
"I really appreciate the president himself being here and putting the focus on and the spotlight on probably the worst tragedy that California's ever faced", Brown said.
A canyon home was left untouched amid the surrounding charred and blackened hillsides from the Woolsey Fire along Lobo Canyon Road in California.
"The efforts are still very active", said Daniel Ramey, a Cal Fire officer.
Authorities stressed that the long roster does not mean they believe all those people are missing.
Some rain was expected in the Butte County area on Tuesday which could help put out the fire, but there were fears there could be floods or landslides in areas where the trees and vegetation have been razed.
With more than 12,700 homes and other structures up in smoke, many refugees have taken up temporary residence with friends and family, while others have pitched tents or were living out of their vehicles.
Camp Fire death toll rises to 76, sheriff says
Authorities said 47,200 people had been evacuated because of the fire and almost 1,200 were living in shelters.
Rescuers with sniffer dogs have been conducting a painstaking house-to-house search.
"It seems that many more people are missing than anyone thought even possible", Trump told reporters in Washington, saying he looked forward to meeting fire responders and firefighters who have been "incredibly courageous".
Some news sources were quick to point out duplications or odd anomalies in the county's list, including an earlier version which listed five missing people as aged 119, according to the New York Times.
"This has been a tough day when you look at all of the death from one place to the next", Trump said Saturday before flying back to Washington.
"I don't think it's appropriate for any of us to sit and speculate about what the future holds", he said.
The death toll was at 71 as of November 16, according to the Butte County Sheriff's Office, which also said that it had identified two sets of human remains as Paula Dodge, 70, and Randall Dodge, 67, both of Paradise.
Sheriff Honea said that because of displacements, many of those on this list may not even be aware that people are looking for them.
If they did make it out, older residents may also be less likely to have access to the internet or other mobile communications to contact people they know. The blaze has now burned 148,000 acres and is 55 percent contained.
Fire officials said all possible causes besides human activity have been ruled out in that fire, and authorities have announced a $10,000 reward for information leading to anyone responsible for the wildfires.
