Blazes in the US West have blocked a major route to Yellowstone National Park during tourist season and tore through a mobile home park in Utah, leaving residences destroyed and people displaced.
High winds pushed a northern Utah brush fire out of a field and into a neighborhood, destroying at least 10 homes in trailer park.
Authorities were investigating Wednesday whether the 30-acre fire in the city of Tooele was intentionally set because they said it appeared suspicious.
The fire that ignited Tuesday has been contained but has displaced several dozen people. Eight other homes and a handful of cars were damaged.
Three firefighters and one resident were treated for smoke inhalation, but no other injuries were reported.
Resident Javier Cortez, who has a family of six, told Salt Lake City news station KUTV that he smelled smoke and ran outside.
His family tried to use a hose to wet grass around their home but they were forced to run from the flames, Cortez said. Their home of four months was destroyed.

Crews are battling a blaze blocking a route to Yellowstone National Park and the region of Jackson Hole as summertime visitors flock to the popular northwest Wyoming areas.
The wildfire has burned about 12 square miles in the Bridger-Teton National Forest and closed a 40-mile section of U.S. 191/189, a highway heavily used by travelers heading across Interstate 80 to the park and Jackson Hole.
That stretch of highway is used by an average of 2,600 vehicles a day during July. The region includes the resort town of Jackson, Grand Teton National Park and other outdoor recreation.
But alternate routes are available, including I-25 through Casper. The fire is burning about 5 miles north of the community of Bondurant.
New fires also broke out in remote areas of national forests in the western part of the state.
Authorities took aim at a fast-moving wildfire in southwest Idaho and slowed the flames Wednesday.
Officials called in retardant bombers and additional firefighters to strengthen containment lines around the blaze burning in grass and sagebrush 15 miles east of Boise.
The human-caused fire that started Tuesday has ballooned to about 7 square miles, destroying a barn and two smaller structures, but no homes are threatened, fire spokesman Brandon Hampton said.
A wildfire threatening homes just south of Alaska’s largest city was likely caused by people, fire officials said.
The fire came within a mile of two separate Anchorage subdivisions, fire incident commander Tom Kurth told reporters Wednesday. There are no immediate plans for evacuations, but he said residents in affected areas would be wise to be ready to go if necessary.
More than 20 homes are threatened and the area about 10 miles south of Anchorage that is heavily used for recreation, officials said.
Kurth said fire managers are anticipating a change in the hot, dry weather, with Thursday’s forecast calling for up to a half inch of rain for the area.
