I think this is probably Rosa webbiana and IF the images were from Ladakh, I would say, almost certainly is this species but one has to consider Rosa macrophylla in Lahaul and presumably Spiti (which I have seen above Koksar, as well as at lower levels on the Rohtang). Images not close enough to be certain.
These two species can be difficult to tell apart. In Lahaul the flowers were used by doctors of Traditional Tibetan Medicine against stomach ache, also used as ornaments and in bouquets to decorate temples. The thorny twigs are wrapped around young trees to protect them from goats and as fencing especially when Hippophae is not available.
