Another glacial lake
One of my favourite photos of a glacial lake margin. This is from South Georgia -- photo by Chalmers Clapperton. Note that this lake has a wildly oscillating surface -- it's quite probable that these shorelines are not in a tidy time sequence at all. Also, note that the strandlines are well marked where the rocky slopes are relatively gentle, but less well marked at the far end of the lake where there are quite active scree slopes.
