Abstract

Dendrochronological analysis and radiocarbon dating show that a break through to the sea occurred along the lower course of the Horton River after 1640 AD. At the breakthrough site, the Horton River flowed 10 m above sea level so that river erosion and delta building would have been rapid. Construction of the delta has protected the adjacent sea cliffs from wave erosion. Attention is paid to the nature of geomorphic change in a permafrost environment and the role of river and sea ice in affecting changes
