Whereabouts in Spiti were you. Looking south from Parang La last year there seemed to be peaks similar to this on the far side (south) of the Spiti Valley.

This was looking north from Chattru (or just east of Chattru anyway). I've find this peak on google earth and it's approx 5370m. There's so many amazing peaks like this along Spiti, I can't wait to go back.
