Rivers and Glacial Valleys

 

Alaska is full of glacial terrain, in the area I was in had U shaped glacial valleys that were formed by glacial erosion.

Caption: This is an intermittent braided river in Denali National park. There are also excellent examples of the bedload in between the streams that this river carries when the water level is raised due to mountain runoff.

This meandering river shows the cut backs and deposition along the banks of the river that have been formed by the meandering amplitude. 

While the braided river isn't necessarily a form of transportation for locals since it is intermittent, some of the larger perennial meandering rivers serve as resource transportation from town to town, whether it is via boat or river plane travel.
