  • Griffith Taylor's palimpsest theory of the Dry Valleys of Victoria Land, Antarctica
  • Griffith Taylor was the first geomorphologist to work in the Dry Valleys of southern Victoria Land, Antarctica. He proposed a multistage model in which earlier cirque erosion was later swamped by expanding outlet glaciers. Subsequently
  • these glaciers retreated leaving the present form of the valleys. The topography retained the imprint of each episode, hence his name palimpsest theory. The A. summarises later research and compares Taylor's theory with current views.
