Abstract
Southeast‐northwest trending longitudinal ridges are conspicuous morphological features at Lågjæaren, southwest Norway. They have been interpreted as either marginal push‐moraines, deposited by a southwesterly flowing glacier, or drumlins, which originated during advance of a northwesterly flowing glacier. The paper presents results of morphological, sedimentological and glaciotectonic analyses of one of these ridges at Obrestad. It is suggested that the ridge has been formed by drumlinization of outwash deposits by a glacier advancing towards the northwest and subsequently deformed by a southwesterly flowing glacier.
