The photo above shows a view of AJ falls, just off the East Glacier Trail, in Mendenhall Glacier National Park, near Juneau, Alaska. This is actually a manmade waterfalls, created during the gold rush a little more than 100 years ago. At that time, this area would have been fairly close to the eastern edge of the Mendenhall Glacier. At the lip of the falls, this valley seems much too small and steep to be considered glacially scoured. However, ice probably flowed over the edge of the waterfalls here and perhaps plucked rock from the fall's face. The lower third of the rock wall shows markings that likely result from differential weathering on what appears to be either the foliation of metamorphic rock or possibly the bedding of a sedimentary rock. Photo was taken on April 17, 2004.
