Glacial Trough
Lateral + Vertical erosion of valley
Straight, steep sided trough
Traditional U shape (Parabolic)
Truncated Spur
Interlocking spurs truncated by valley erosion
Truncated spur formation
Vertical erosion forms interlocking
Lateral glacial erosion
Processes weaken + remove debris
Parabolic valley forms
Hanging valley
Tributary valley perpendicular to main trough

Ice deformation around an obstacle
Differential geology
Crag and Tail
Differential erosion
Highly resistant rock (Crag)
Protected less resistant rock (Tail)
