In some places, the layers would go straight up, form an upside U shape, and come back down. We were in the middle of the growing season and the flowers were incredible. They have wild roses with incredible fragrance. Fields were full of flowers and one day we camped in one. It was great except for the person with hay fever.
People live here, even at the high elevations.
There are small villages, sometimes only 4 houses. They grow barley and we were in the middle of the growing season. They use Yak dung for heating and cooking. Everyone is out collecting yak dung and they pressing it into large plate shaped forms, and drying it for the winter. However, in an incredible collision of technology, most houses have solar collectors for electricity.
