(Williamstown, MA) — The outdoor fire which is impacting East Mountain in Williamstown has grown to 800 acres. That according to an update by the Colrain Fire Department, which was part of a 20 man crew of Franklin County firefighters who spent their fourth day yesterday battling the blaze digging hand lines to prevent further spread. The fire is believed to be the largest outdoor blaze of its kind in Massachusetts in the last decade.
