Glaciers and New Yorks Economy

• Thick, fertile soils developed on till and
  outwash foundation of agriculture in state
• Microclimate associated with Lakes
• Water moderates climate
• Warmer in winter, cooler in summer
• Ideal for growing grapes/producing wine
• Aquifers especially in outwash
• Sand and gravel for construction
