In the fall of 2011, the dogsled trails were moved from the vicinity of Sunday Creek in Algonquin Park to the vicinity of the portage leading to Blackfox Lake from Hwy. 60. That is, parts of the Blackfox portage were reconstructed as a dog sled trail. For further information see Blackfox L. Portage and Sunday L. Dogsled Trail.
This gallery illustrates a late fall hike (2011 Nov 15) along the portage and shows the damage caused by the reconstruction.
