Environmental Effects
Snow grooming and the associated snow packing is known to have negative effects. The compaction reduces porosity, permeability and water holding capacity of the mountain slopes, while heat flow rates and length of snow retention are seen to increase. This combines to produce longer and deeper frost penetration into the soil, causing negative effects on the underlying tussock. It is suggested that the compacted areas be marked and shifted over time to reduce the ecological effects.

Famous quotes containing the word effects:
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
