Monoculture Deodar forests near Harsil on Gangotri route, as seen aerially along blue-green Ganga

A monoculture of Deodar forests near Harsil on the Gangotri route is seen aerially along the blue‑green Ganga, from the Uttarakhand inner Himalaya. A steep re‑entrant ravine shoots down a hill slope between Deodar or Himalayan Cedar forests on both sides, with rough stone and glacial rockfall debris running down the chute.
