• Outwash sands and gravels:

  • Meltwater rivers erode moraine deposits in spring and summer 
  • River channels build up with sediment creating a braided river 
  • Sorted by size 
  • Softer minerals removed by abrasion 
  • Rounded 
  • Imbricate and cross bedding 
  • Organic remains possible
