Granite
  • LAND USE
  • Granite areas are of limited value for farming due to too much acidity and surface water, but they provide:
  • Good terrain for grouse and for military training.
  • Good for reservoirs because they are impermeable (water can’t get through)
  • Tors and bogs are great tourist attractions
