As the Panj river junction was approached the river narrowed and became more turbulent and grass was at last visible. We did not know it at the time (August 11, 2010), but the turbulence of the river reflected the delay in summer snow melting. The levels of all the rivers were exceedingly high. This delay was a substantial factor in creating the floods in Pakistan which were just starting to take place. We learned about them later. The notion that something might be abnormal came to us suddenly as we rounded a curve in the road into a side valley.
