About Pukaskwa
Pukaskwa — pronounced PUCK-a-saw — protects the wildest stretch of Lake Superior shoreline left in Canada. The 1,878 km² park sits at 48° north, with no roads through its interior and only one access point. The aurora here is not a forecast event so much as a feature: on any clear night with Kp ≥ 3 you'll see green wash on the northern horizon, doubled by the lake.
