Rainfall far above normal for mid-June, combined with a glacial lake breach above Kedarnath, sent walls of water and debris down narrow Himalayan valleys packed with pilgrims and tourists.
Entire market streets and lodges were swept away, roads and bridges were destroyed, and tens of thousands were stranded in high-altitude valleys for days. The Indian armed forces conducted one of the largest civilian air rescues ever attempted in the region.
The disaster prompted scrutiny of unregulated hotel construction on riverbanks and hydropower development in a fragile mountain environment.
