"Since the valley is an environmentally sensitive zone, deep excavation might not be possible to look for skeletons. Therefore, technological help shall be required after the snow melts," Chief Minister Harish Rawat told reporters during a visit here yesterday.
Even after nine months of the disaster, the exact extent of loss is yet to be ascertained as the damage was done to lives and property on a massive scale, he said.
The chief minister said he was confident that the damaged roads to the Himalayan shrines will be completely repaired and the char dham yatra will begin on time.
The char dham yatra is scheduled to begin on May 2 with the opening of the Gangotri shrine.
