MAPLETON, Maine (AP) Maine game wardens say a 25-year-old snowmobiler was killed in a crash in Mapleton.

Officials say Brian Buck Jr., of Mapleton, failed to negotiate a curve Saturday night and struck a large snowbank on the side of the trail.

The snowmobile became airborne and tumbled end-over-end before coming to rest on its side. Buck was thrown from the snowmobile and suffered fatal injuries.

An initial investigation by the Maine Warden Service found excessive speed appears to be the major factor in the crash.
