I snowshoe often and would be willing to help out grooming the trails whenever needed as I live ~10 mins away. Is there any technique or is it as simple as walking the trails? Would it only be needed after a snowfall or would snowshoeing damage the trails when already compacted?
Any and all help getting the trails packed is appreciated. It really is as simple as walking the trails.
Snowshoes will not damage the trail at any time, even if they are already packed.
It really is as simple as getting the air out of the snow. Once it is compacted and the air is removed, it is not hard right away. But after it goes through an evening of cold it hardens up to form a great surface.
The same as with XC ski grooming. If you go on a trail right after grooming it is like being on soft sand. The same trail a day later is a very firm surface. Not like pavement, but firm enought to walk leaving only maybe a 1" imprint.....not that you should be walking on XC trails :P
