After the unseasonably warm, rainy weather, the skating section of parkways has hardened considerably from P10 to Champlain lookout as well as in the other direction, to Black's hill. I stayed in the middle of the parkways where the surface was fairly flat as there is considerable skidoo and heavy machine tracking to either side.
A very, very light snow shower made the upper portion of the parkway more enjoyable.
Poles did not sink through the surface on the way to the Champlain lookout, but this was not the case from the Fortune road intersection to Black's hill.

Classic tracks are somewhat eroded, bu skiable.
