Where roughly does Rose Route go?

Good question! A bit of traditional mountain route this, follow your nose.
We started up the easy-angled slab on the lower right, up then traverse back left to the bottom of the main upper buttress. Then it basically follows the right edge of the buttress to the left of the large grassy rake. Open to interpretation I think, good rock lower down but a bit vegetated higher up.

Thanks. Psyched!
