The three photos here show examples of glaciers with flow that is restricted by pre-existing topography; the topography dictates where the ice flows, and the ice flows down pre-existing valleys. Thus, these are all examples of valley glaciers.
The top left photo shows just one valley glacier that is clearly flowing downhill. All valley glaciers flow downhill.
The downhill flow of ice is also evident in the top right photo where several valley glaciers merge to form a single large valley glacier. This valley glacier has retreated from its maximum size, and you can tell this by the fact that the valley downstream from the glacier terminus is U-shaped.
valley glacier in the foreground of the bottom left photo is the result of two smaller valley glaciers merging; you can see the two
smaller valley glaciers branching off to the left and the right toward the back of the photo. Although the topography in the bottom left photo
appears flatter than that in the top two photos, this ice is still flowing downhill.
