The Little Ice Age maximum in the Southern Alps, New Zealand: preliminary results at Mueller GlacierDepartment of Physical Geography, University of Trier, D-54286 Trier, Germany Lichenometric-dating studies using the yellow-green Rhizocarpon subgenus at Mueller Glacier in the region of Mt Cook, Southern Alps, New Zealand, reveal a Little Ice Age maximum about ad 1725/1730. Differences from previous studies are shown to result from different methods, especially the type of mathematical functions used for calculating the lichenometric dating curves. Previous work also used variable sample sizes, distal moraine slopes, and, to some extent, different fixed points. Schmidt hammer measurements enable the differentiation of Little Ice Age from pre-Little Ice Age frontal moraines in the outer glacier foreland and confirm the status of the Little Ice Age as a separate glacier advance among several advances during the Holocene.
