Description :
The aim of this paper is to show how digital terrain modelling using high-resolution lidar (Light Detection And Ranging) data of Whidbey and Camano islands, combined with an understanding of process-form relations can be used to provide information on the uplift pattern in the northern Puget Lowland. The AA. provide height information from lidar data of sea level indicators along a transect oriented N-S, roughly parallel to the direction of ice movement. In addition, they present geomorphic information that relates to the ice flow directions of these islands to provide information of the melting history of ice in this area.
