Residents have taken to social media to share pictures of numerous dumps over the past fortnight, with tyres and building material among the latest rubbish left on the hill.
Dangerous asbestos had now been found among the litter, on the popular walking area. The council has urged people to stop dumping in the area, and has already moved the dangerous material.
The dumps come just a few weeks after the council changed its recycling centres.
The revamp has seen a new recycling centre located at Hortonwood 50 and improvements to the existing site at Halesfield, following the closure of Ketley and Granville at the weekend.
The borough now has two recycling centres – the new one at Hortonwood serving the north of the borough and one at Halesfield serving the south. The sites are open 9am to 5pm, seven days a week, 362 days a year.
Russell Griffin, a spokesman for Telford & Wrekin Council, said: "Fly-tipping is a crime and we ask our community to help put a stop to it by being our eyes and ears.
"Offenders can, and will, be prosecuted."
