Satellite images have captured the extent of the devastation caused by wildfires in Texas.
The unbridled Smokehouse Creek Fire, the largest of all the blazes, has been burning since Monday.
It has spread to the Oklahoma border after starting near towns northeast of Amarillo – and the weather forecast for the weekend threatens to fuel it further.
At least one person, an 83-year-old woman in Hutchinson County, was reported by local media to have died in the blaze.
Firefighters managed to carve containment lines around just 3% of the fire as of Wednesday night, officials said.

An area covering 1,300 square miles – equivalent to twice the size of London – has been burned so far, making the Smokehouse Fire the second largest in the state‘s history, only just smaller than 1,400 square miles burned in a 1996 blaze.
US space technology company Maxar Technologies has shared images of the wildfire from above, highlighting how widespread the fire – which is one of several burning in the state – has been.
Cooler temperatures are expected on Thursday with a chance of rain, which gives firefighters a chance to increase containment ahead of another increase in temperatures over the weekend.

Authorities have not said what ignited the fires, but strong winds, dry grass and unseasonably warm temperatures have fed the flames.
Nim Kidd, chief of the Texas Division of Emergency Management, said the weekend forecast and “sheer size and scope” of the blaze are the biggest challenges for firefighters.
“I don’t want the community there to feel a false sense of security that all these fires will not grow anymore,” he said. “This is still a very dynamic situation.”

Flames have been pushed by powerful winds across the sparsely populated region, with smoke delaying aerial surveillance of the damage in some areas.
