Jan 30 2021,


No new snow with trails in overall Good groomed conditions. We still really need a good heavy snowfall. The forecast does not look promising so stay tuned on snow conditions and grooming results.  There is a large amount of snowmobile traffic and we are seeing signs of the snow getting tired. Some areas were already showing “sugary” signs when trying to get a good grooming ribbon. North of Shingleton was flattened out but hard and thin with little to work with closer to Shingleton, expect to see some gravel mix in areas. Some tight corners are getting icy throughout our area so ride with caution. Trail 422 has vehicles still driving on Miners Castle Road. Trail 419 between Munising and Wetmore is rough with a challenging creek crossing and no snow to work with, ride with caution. Please respect residential property owners and STAY ON THE TRAIL, No Snowmobile Signs mean just that. Please continue the snow dances and Stay Tuned for updates!

Past 24 hour Grooming Operations: Trail 8 from 7 miles North of Shingleton West to Trail 417, Trail 7 North, Trail 7 South to Doe Lake Road, Trail 418, Trail 419 from Trail 8 into Wetmore, Trail 419 West, Trail 422 and Wetmore Spur   (reference map below for trail locations)
