@melissafarlow | Fresh morning snow on trees along the Mendenhall River near where it is changing course. As it meanders through a valley below the glacier, an uplift raises Juneau higher. The river may become a half-mile shorter but it will likely then get longer again. Over time, it will move downstream carving a new path back and forth according to University of Alaska geology students who are measuring the glacial river’s natural process. @thephotosociety #alaska #snow #winter #Mendenhallriver #glacier #Juneau
