The sides of mountains prevent valley glaciers from spreading in all directions as continental glaciers do. These glacial troughs may be several thousand feet deep and tens of miles long. large boulders transported by ice. What is a Valley Landform? a long, knife-edged ridge that was a divide between 2 glaciers. As each glacier erodes either side of the ridge, the edge becomes steeper and the ridge becomes narrower.
