Abstract
A core from Prince of Wales Island in the central Canadian Arctic was analy sed for pollen and sediment characteristics. From 9200 yr BP to 7000 yr BP, the landscape supported a pioneer vegetation under cold conditions, with r elatively high sediment input to the lake. Between 7000 and 4000 yr BP ther e was a period of high pollen concentrations, more abundant Cyperaceae and Dryas an the landscape and finer sediment input. In the last 4000 years, cl imate cooling is indicated.
