It is a feeling difficult to explain but easy to experience once you go there. The trip to Kaza was full of dry mountains made of loose soil and gravel. The Spiti valley is extremely wide with a thin stream - the Spiti river flowing in the middle. There are patches of vegetation like wheat fields around villages near the river. The mountans are dry and the composition is so loose that we saw small stones or gravel roll down the slope on many occasions.
Many hills look more like huge termite mounds .
Infact that is way it is not recommended to drive at night in these roads. But our driver Sher Singh was a brave heart and because of him we kept going in the night and reached Kaza at 4200 metres altitude, at around 10 pm. He had to drive carefully and we kept looking with torch above in the slopes for any loose soil or stones rolling down on us . We infact had two narrow escapes though the stones were not bigger than 10cm dia. After Reotang-peoh, we hardly moved on metalled road.
