From EARTH Magazine, 10/13/2015 -- Typically, mountains get steeper with increasing altitude. However, during the Pleistocene, a geologic epoch with extensive glaciation, the tops of some mountains, like the Alps, were scoured away. This left mountains that were steeper at a lower elevation than they were at a higher elevation.
