The cause of a peat bog fire in Borth, near Aberystwyth, is still unclear.
Fire crews were called to the blaze in the area at 5.20am.
According to Dr Christian Dunn from Bangor University peat burns well because it's made of rotting plants.
He added that it is unusual to see such a fire at this time of year.
Our reporter Kevin Ashford sent this report:
There has not been a fire of this size on the Borth peat bogland for 20 years, according to Natural Resources Wales.
The Borth bogland is regarded as one of the most extensive lowland peat bogs in Britain.
The vegetation is mostly made up of purple moor grass, called Molinia.
Natural Resources Wales said that although the outside of the grass may be wet, the inside could be dry.
"The Molinia has probably been set alight by sparks or flames from damaged power lines. Molinia fires are not uncommon in dry weather in autumn and winter and can be set off by a discarded match or cigarette.
"The peat will be saturated with water and we believe that the fire has moved quickly through the vegetation without burning the peat."
This picture of the bog fire in Borth was taken at around five this morning, when firefighters first began to respond to the incident.
The cause of the fire is still not known. It has now been extinguished.
