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.
