Glaciated Formations

?

Hanging Valley

Truncated Spurs
  • Tributary valley feed into the main valley
  • Main valley erodes quicker than tributary valley, leaving the tributary valley higher up
  • Cut-off rounded areas of land
  • Formed when a glacier cuts through interlocking spurs

Roche Moutonnees

Ribbon Lakes
  • Indicates direction of ice flow
  • When there is resistant rock, the glacier moves over it
  • Abrasion occurs creating a smooth layer of rock
  • Meltwater flows down the other side, seating into the cracks in the rocks and freezes
  • Plucking occurs creating a rough edge
  • Occurs when there are different types of rock, some are less resistant than others
  • Less resistant rock erodes more quickly that resistant rock, creating a hole
  • Glacier melts, leaving behind a lake
