Last year I bought a book on ancient rock paintings in Finland. One of the best paintings in Finland is nearby, but very hard to reach. With the recent low temperatures, Jarmo and I figure we could cross the lake to go see it.

Per the book and Retkipaikka article, the summerhouses next to the rock with the painting block access from the obvious southern direction, and recommend taking a 2km ski from the other side of the lake. We figured we could actually cross the lake from a shorter route on foot, using the route marked with red below:
