Glaciation was much more extensive in the past, when much of the world was covered in large, continental ice sheets. Most glacial valleys were originally formed by stream erosion and then widened as the glacier eroded the valley walls. Originally, truncated spurs are created as a river erodes the upper valley it cuts down into the rock and meanders in and out of the surrounding rock. The passage of glacial ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the stoss (upstream) side of the rock and plucking on the lee (downstream) side.
