Varves are best developed near glaciers because they represent light colored layers of coarser material deposited in the summer when the streams issuing from glaciers have more energy to erode coarser material compared to the fine silts and clay of the winter months when there is very little flow and very little erosion. They mostly occur in glacial lakes.
