Nearly 20,000 years ago, a 5-km-long Himalayan glacier “abruptly” changed course and over time fused into an adjacent glacier in present day Pittoragarh, Uttarakhand. This is the first time, say scientists who have described the findings in a peer-reviewed journal this week, that such a turn in glacier’s course has been recorded in the Himalayas. Change in climate along with tectonic movement probably caused this to happen.Based on remote sensing and an old survey map, the study, which appears in the Journal of Geosciences, assessed that the glacier had been affected by active fault and climate change.
