Similar to the U-shaped valley. Erosion such as plucking, abrasion and freeze-thaw causes it to grow in size - getting wider and deeper.
Ice just 'powers' through meaning it is straight and doesn't have interlocking spurs
Truncated spur was an interlocking spur that the ice was destroyed (plucking and abrasion)
Hanging Valley is a tributary valley with the floor at a higher relief than the main channel into which it flows.
Ribbon lake - found at the bottom of a glacial trough
Ribbon lake is formed where the soft rock is and leaves the hard rock (resistant rock) on either side - wide, flat valley floor
