Résumé

Four measured sections of unconsolidated Pleistocene strata exposed on the Yukon coast between Shingle Point and Herschel Island are described. The sediments have suffered ice thrust deformation and are unconformably overlain by fluvio-glacial retreatal gravels. The results of palynological examination, study of mollusca and a new 14C determination are discussed. Deformation of the coastal strata probably occurred between 37 900 and 9510 years ago.
