The State Disaster Response Force (SDRF) team has reached Bageshwar district headquarters and is likely to reach the glacier, at a height of 4320 metres, in four days, Kapkot SDM Ravindra Singh said.
Bagish Chandrakar (29), a businessman from Raipur in Chhattisgarh, last spoke to his sister on September 5, the SDM said.
Local villagers, too, said they spotted him last on September 5 at Jatoli camp, 80 km from Bageshwar, Singh said.
Chandrakar's family members have also requested the authorities to provide a helicopter to the search team.

"We have sought a helicopter for the search team, without which tracing him in the vast snowy terrain of Pindari and Sundandhunga would be difficult," said Priyank Patel, a relative of the missing trekker.
The locals fear that the trekker must have lost his way and hit a rock or became a victim to the wild bears or the biting cold, Singh said.
Registration of trekkers at Jatoli camp is not compulsory and Chandrakar did not inform the local administration prior to his high-altitude trek, the SDM added.
