MARQUETTE — Speed was a factor in two separate snowmobile accidents yesterday in the Upper Peninsula.

The Marquette County Sheriff’s office says a downstate man was struck by a snowmobile on trail #5 in Humbolt Township just at 3:40 p.m.

62-year-old David Daniels of Grand Haven was traveling east on the trail when a snowmobile in a group stopped in front of him near a bridge crossing. Unable to stop in time, Daniels attempted to go around the stopped snowmobile and struck 73-year-old Richard Hartigan of Howell who was traveling east on the trail.

Hartigan was transported to U.P. Health Systems Marquette. Daniels sought his own treatment for injuries.

Powell Township EMS and Fire #161 and U.P. Health System East assisted at the scene.

On trail #14 west of Big Bay, the Marquette County Sheriff’s office says a 69-year-old Wisconsin man heading west on the trail in a group of three snowmobiles was unable to negotiate a curve.

David Noffke suffered a lower extremity injury when he drove off the trail. He was transported to U.P. Health System Marquette.

The crash occurred about 14 miles of Big Bay at 1:50 p.m.

Humbolt Township Fire/EMS, Michigan DNR and U.P. Health System West assisted at the scene.
