Mussoorie, Aug. 6 -- Light to heavy rainfall lashed Uttarakhand on Wednesday, triggering landslides and boulder falls that disrupted sections of the Char Dham pilgrimage routes, while a massive boulder crashed into a colonial-era government quarter in Mussoorie, injuring a woman and narrowly averting a major tragedy. The boulder broke off from a hillside during continuous rain and slammed into a government residential unit located inside the sub-divisional magistrate office complex in Mussoorie on Wednesday.The rock tore through a sidewall and entered the living room of government employee Govind Singh Negi. While the family escaped serious injuries, Negi's wife, Reva Negi, sustained minor injuries after bricks from the damaged wall fell near her bed. "A large boulder struck the wall of our house early in the morning and damaged a portion of the structure. It was a miraculous escape for my wife, who suffered minor injuries after bricks fell close to her bed," Negi said. The affected family has shifted to a safer location nearby amid fears that the damaged structure could collapse during another spell of heavy rain. Residents of neighbouring quarters have urged the authorities to undertake scientific treatment of the hillside and repair the ageing buildings. Mussoorie SDM Rahul Anand said directions have been issued to repair the walls and construct a retaining wall behind the house to ensure the safety of government employees. In Uttarkashi district, the Yamunotri National Highway near Syanachatti was temporarily blocked on Wednesday morning following landslides and boulder falls. Personnel cleared the debris and restored traffic by around 10 am. Monsoon-triggered landslides also disrupted vehicular movement in Tehri district, leaving six motor roads blocked. National Highway 707A near Jeevan Ashram on the Mussoorie Bend-Kempty route was affected by heavy landslides and boulders, prompting the deployment of heavy machinery to clear debris. Several irrigation channels in Jaunpur tehsil, including those in Aindi, Khaskoti, Pavet and Gharada villages, were damaged. A pedestrian pathway connecting Aindi and Piftausi was also affected, while heavy rains disrupted the drinking water supply pipeline in Parogi village. In Rudraprayag district, the Alaknanda river touched 626 metres at 7 am, just one metre below the danger mark of 627 metres.
