Glacial Landforms and Processes


I.   BASIC CONCEPTS AND TERMINOLOGY

A.   Glacier: Continental (satellite - long range) (satellite - closer) ( aerial view ) vs. Alpine

  1. highland icefield (Bagley Icefield) (#3)
  2. nunataks (#2) (#3)
B.   Process
  1. zone of accumulation (top or head)
    • weight / pressure
    • snow - firn - ice
  2. zone of ablation (bottom or toe)
  3. flow-like movement (Alaska) ... (French Alps) ... under glacier
  4. abrasion .... example #2
  5. plucking
  6. crevasse (close up)


II.   LANDFORMS

A.   Continental Glaciation

  1. till (another)
  2. kettle (satellite #1) (satellite #2)
  3. drumlin (diagram) (map) (example) (profile view)
  4. moraine #2
  5. icebergs (calving) (#2) (video)
  6. iceshelf ... example ... close-up
B.   Alpine Glaciation
  1. moraine
  2. glacial canyon ("U" shape) (Yosemite)
  3. hanging valley (Canada) (Montana)
  4. cirque (diagram) ... photo: Alberta
  5. arete ... another example ... video (1:30 to 6:00)
  6. horn .... another example
  7. col....Mt. Everest
  8. tarn .... Juneau ... Wales ... Colorado
  9. erratics: process ... Germany ... NYC ... Washington
C.   Fjords ... example #2
