An Andover man was killed Thursday night in a single snowmobile crash on a trail near Roxbury Notch Road, according to the Maine Warden Service.

Gregory Simmons, 47, of Andover was killed when it appears he lost control of his machine on Interconnecting Trail System 84 and was ejected, according to a statement Friday morning from Maine Warden service spokesman John MacDonald. A snowmobiler who found the crash scene reported it at 9 p.m. Thursday, according to McDonald’s statement.

Simmons was riding a 2006 Arctic Cat F6 home from the Knotty Moose restaurant, according to wardens.

Game wardens say speed appears to be a contributing factor and Simmons was wearing a helmet.

Roxbury, north of Rumford, is home to several ATV and snowmobile groups. Rescuers were attempting to round up snowmobiles from local groups and fire departments as their efforts got underway.
