India uses thermal imagery in glacier rescue effort

Sunday's disaster below Nanda Devi, India's second-highest peak, swept away the small Rishiganga hydro-electric project and damaged a bigger one further down the Dhauliganga river being built by state firm NTPC.

Chamoli District Magistrate, Swati Bhadoria said the death toll had climed to 29. She said that State Disaster Response Force personnel were using a zipline to reach areas and provide support to those who were cut off after the glacier burst.

Most of the missing were people working on the two projects, part of the many the government has been building deep in the mountains of Uttarakhand state as part of a development push.
