Here's a look at some of the deadliest U.S. tragedies to have claimed the lives of wildland firefighters, including the 19 killed in an Arizona blaze Sunday:
June 30, 2013: Nineteen members of an elite crew were killed in a fire northwest of Phoenix that lit up the night sky in the forest above the town of Yarnell. The fast-moving blaze fueled by hot, dry conditions is the deadliest wildfire involving firefighters in the U.S. for at least 30 years.
Aug. 5, 2008: Nine people were killed when a helicopter crashed shortly after taking off with a load of firefighters heading back to camp in Northern California. Seven of the dead were firefighters with Grayback Forestry Inc. The crew was fighting a forest fire on the Shasta-Trinity National Forest outside Redding, Calif.
Oct. 26, 2006: Five firefighters assigned to San Bernardino National Forest Engine 57 were fatally burned when fierce Santa Ana winds blew the Esperanza Fire over their structure-protection position at Twin Pines in the San Jacinto Mountains.
Aug. 24, 2003: Eight contract firefighters who had spent two weeks fighting an Idaho wildfire were killed on their way home when their van collided with a tractor-trailer and exploded into flames outside Vale, Ore. The firefighters, all men, worked for First Strike Environmental, a contract firefighting company and all were from Oregon.
July 6, 1994: A blaze near Glenwood Springs, Colo., killed 14 firefighters who were overtaken by a sudden explosion of flames. The lightning-sparked Storm King Mountain blaze roared through shrubs as the firefighters scrambled uphill. Thirty-five firefighters on the mountain that day survived.
June 26, 1990: The rapidly spreading Dude fire in the Tonto National Forest near Payson in eastern Arizona trapped 11 firefighters, killing six of them.
July 9, 1953: The Rattlesnake fire in Northern California took the lives of 15 firefighters battling a blaze in Mendocino National Forest.
Aug. 5, 1949: The Mann Gulch fire near Helena, Mont., killed 12 smokejumpers and a forest ranger after they were overrun by flames. Their story was memorialized in the book "Young Men and Fire" by Norman Maclean, who also wrote "A River Runs Through It."
Oct. 3, 1933: The Griffith Park wildfire in Los Angeles killed 29 firefighters.
