Notes on the Shoreline Recession Along the Coast of the Yukon Territory
The 150-km.-long stretch of the coast between Herschel Island and the Mackenzie Delta terminates in bluffs cut into Pleistocene silts, sands, and gravels. No bedrock has yet been observed; if present, its occurrence must be very local. The coastal bluffs which are up to 50 m. high, are constantly be...
