:| that's a relatively small scar on the landscape, is about 2 big trees wide at the widest spot, I think the forest might survive.
... but if you added that damage to all those other little trails you would have a serious problem. Those are quad trails you see, not motorcycle tracks.
Not sure if the picture is of the hill though it probably is.
According to the GRCA website: All trails leading up Lookout Hill remain closed while the Ganaraska Region CA and it’s partners continue to focus on site rehabilitation and erosion control.
