(PA) -- It was one of several blazes that sent thousands fleeing homes across the US West during a blistering holiday weekend heatwave.

In Oregon, crews rescued about 140 hikers forced to spend the night in the woods after fire broke out along the popular Columbia River Gorge Trail.

Search and rescue crews air-dropped supplies as flames prevented the hikers’ escape.

Wildfires also burned in a 2,700-year-old grove of giant sequoia trees near Yosemite National Park, forced evacuations in Glacier National Park and drove people from homes in parts of the West struggling with blazing temperatures.

Los Angeles Mayor Eric Garcetti declared a local emergency and at the state level, Governor Jerry Brown did the same for the county after the wildfire destroyed three homes and threatened hillside neighbourhoods.

More than a thousand firefighters fought flames that destroyed more than nine square miles of brush-covered mountains as authorities issued evacuation orders for homes in Los Angeles, Burbank and Glendale.
