Here are 10 tips to minimize impact while riding snowmobiles:

* Ride only in areas where snowmobiling is permitted.

* Avoid areas with inadequate snow cover, where young trees and plants are visible.

* Stay on trails wherever possible. Snowmobiling on groomed trails causes no harm to the soil beneath the snow.

* To minimize harmful emissions, keep your engine in tune and use only recommended and certified fuels, lubricants and additives.

* Protect the sound scape by avoiding unnecessary noise created by your vehicle and not overstaying your welcome in high traffic areas.

* Dispose of all sanitary waste properly by burying it in the snow or packing it out.

* Use a fire pan to minimize impact if you build a fire. Properly dispose of ash and fire debris by packing it out.

* Be respectful of wildlife's winter habitats.

* Remember that designated wilderness areas are reserved for the most primitive outdoor adventure. Motorized and mechanized vehicles are not allowed.

* Pack out what you pack in. Don't litter or bury trash.
