An injured hiker stranded on the Williamstown side of Mount Greylock was rescued late Sunday night.

The Berkshire Eagle  reports several teams of emergency workers brought down the unidentified person seven hours after they responded to a 911 call of a hiker with a broken ankle.

Williamstown forest wardens and the Williamstown Fire Department were dispatched around 3 p.m. Sunday to the Mount Prospect Trail.

The authorities say they immediately requested mutual aid to assist in carrying out the injured party, who was one of three people who were hiking together.

The initial rescue team met up with employees of the state Department of Conservation and Recreation to begin the rescue operation. Once North Adams, Clarksburg and Pownal, Vt., fire departments arrived on the scene, two more teams were sent in to assist Williamstown.

The hiker was taken to BMC for treatment.
