The directions of the ridges differ from most other moraine fields north of Hämeenkangas and seem to reflect an ice recession to the northeast. The morphology and dimensions of the ridges are of the De Geer type, but the composition and structure of the material are somewhat different and refer to possible transportation from both longitudinal and transversal directions. The average distance between the ridges is more than 170 m, which clearly exceeds normal values for De Geer moraine areas in Finland. It is concluded that the moraines have been deposited at or near the ice margin on the wider eastern side of the embayment at Pohjankangas. Their shape and distribution have been affected by abundant meltwaters and the formation of crevasses in the marginal zone.Read More
