Agrass fire blackened much of the Mount Muirhead landmark on Thursday.


The alarm was raised at 4.30pm when a fire was noticed at the southern base of the extinct volcano near Millicent.


At the height of the fire, the CFS issued warnings via social media and radio bulletins.


The blaze was contained a few hours later but CFS crews remained on duty throughout the night to extinguish hotspots and strengthen control lines.


Approximately 29 CFS firefighters worked on the fireground, supported by forest industry brigades and six aircraft, including firebombers and observational aircraft.


The operations were also supported by SA Police and private farm fire units.


The refilling base was the Millicent airport and a Wattle Range Council and a logging company’s water tankers were brought there.


Police said there were no injuries as a result of the fire and nor were there any livestock losses or property damage.


As is standard practice, police crime scene examiners inspected the ignition point and determined there were no suspicious circumstances.


The blackened landmark has proven to be a drawcard for sightseers much to the chagrin of a local resident


“It has been ridiculous how many people are driving down Mount Muirhead Range Road stopping in the grass and taking photos of the burnt mountain,” wrote the resident on social media.


“So, while you are doing this your hot exhaust will catch the grass on fire.


“Please be considerate of the people who have been burnt out and still are trying their best to protect their properties.”
