Along the opposite walls of the Jhong Khola on the trail from Kagbeni to Jharkot, I noticed many cave entrances. Supposedly there used to be a cave settlement here about 2700 years ago. In excavation it has been discovered that they were the homes of a highly developed and ancient Mustang culture. Apparently internal staircases connect many of the caves and some of them are up to nine stories high. In more recent times, lamas have used the caves for religious retreats.
