In the northern hemisphere the broad extent of glaciation had been mostly accepted by the start of the twentieth century, but in New Zealand at that time even the general picture of glaciation was uncertain. Julius von Haast had established that in the South Island the glaciers had extended out considerably from the Southern Alps, but the extent of glaciation in the North Island was unknown. Two rival viewpoints were put forward in 1909. James Park thought that there was a widespread ice sheet, which covered the South Island, Cook Strait and much of the North Island; Patrick Marshall thought that the extent of ice was much less, and argued that much of Park's evidence was spurious. The argument was ‘somewhat resolved’ by a young amateur geologist, Leslie Adkin, who showed that glaciation in the North Island was at most modest, and largely confined to the uppermost part of the main axial ranges. Adkin was a farmer and had no university education, but he published nearly 40 articles in scientific journals on topics as varied as Maori archaeology, and glacial and tectonic geomorphology. This article examines the evidence he adduced for the occurrence of a limited Pleistocene glaciation in the Tararua Range in the south of the North Island, and considers the role of the amateur in New Zealand geology.

This book deals with various interesting aspects of the histories of geomorphology and Quaternary geology in different parts of the world. The papers cover a range of topics: the origin of the term ‘Quaternary’, histories of ideas and debates relating to aspects of fluvial geomorphology (USA and Australia), glacial geomorphology and glaciation (Northern Europe, the Baltic countries, Russia, Iceland, and New Zealand), desert dunes and the geology of Australia, peneplains in China, a palaeo-Tokyo Bay in Japan, together with biographies of Charles Cotton (New Zealand), Valerija Čepulytė (Lithuania) and Česlovas Pakuckas (Lithuania and Poland) that highlight their respective contributions to the disciplines of geomorphology and Quaternary geology. There is an autobiographical contribution from E. E. Milanovsky (Russia) on his work in Siberia, the Caucasus and Iceland, illustrated by his sketches made in the field.
