This isn't really in Jotunheimen, allthough you can see the Rasletind-Kalvehøgdi-massif (which is in Jotunheimen) to the right. The mountain to the left is Bitihorn, and to the right, Synshorn and Fagerdalshøe, neither of which are considered in Jotunheimen. Bitihorn, I guess, is some 10-15 km south of the National Park border.
Still, very nice shot and a very nice place to be!
