Horse carving on cairn, near Minya Konka

horse carving, originally uploaded by mutikonka1.

This is a detail from the cairn shown above. It appears to show a horse [and rider?] tethered to a frame. Note the tassles or balls weaved into the horse's tail - a feature often seen in Kham.

I wonder who took the time to carve this and whether they did it on site or at home and hauled the rock up from way below.
