This is the latest pile of rubbish to be fly-tipped on a South Wales valley mountainside.
Building rubble was left on Gwyrhyd Mountain near Rhiwfawr, near Cwmllynfell in the Swansea Valley. It was spotted by a walker who feared it may contain asbestos.
Celtic Energy, which own the land, hope to have it cleared by the end of this week.
But it is just the latest example of fly-tipping to blight the Welsh countryside, and follows figures which revealed there were more than 35,000 instances of fly-tipping in Wales last year.
The walker said: “I am shocked and disgusted that people feel that it is ok to dump their building waste in a place full of wildlife.
“I understand that you have to pay to dispose of building waste, but surely doing that is better than destroying what makes this area a beautiful place.

“Wales is supposed to be a place for tourism, but this does nothing to help that.
“It looks like building waste, so who knows if there is any asbestos in there?
“I don’t know if it is anything to do with the waste and recycling centres closing, but there is no excuse”
A Commoners Association spokesman added: “Over the last year fly-tipping seems to have increased, and if there has been asbestos, you need to have specialised removal.
“It is a danger to grazing animals, and it is going to deter people from coming to visit the area.”
A waste and recycling centre at Pwllfawatkin in the Swansea Valley closed earlier this year, saving Neath Port Talbot council up to £100,000.
The nearest alternative is at Cwmtwrch on the Powys border.
Will Watson, chief executive of Celtic Energy, said: “Swansea Council enforcement officers are to meet with the Commoners’ Association to see if they can identify the waste.
“It appears to be plaster board and general builders’ rubble. We do not think there is any asbestos.
“We are concerned that this has happened and will do what we can to prevent it in future.”

The dump of rubbish comes as further instances of fly-tipping have been reported elsewhere in the region.
Bags of waste have been discovered in woodland in Pontarddulais by walkers.
Last year, there were almost 1800 cases of fly-tipping reported to Swansea Council . The authority carried out 2,213 investigations and five people were prosecuted.
A spokesman for Swansea Council said: “These instances of fly-tipping are due to be cleared away shortly, and we will be looking for any evidence of where they came from.
“If people do see fly-tipped waste they should contact the council directly, or online”
