Prominent De Geer-moraines had been identified, where the mean distance between the ridges was calculated to 345 m. Furthermore, other glacial formations (drumlins, flutings, rogen moraines and eskers) showed a relationship to De Geer-moraines, either with a similar angle or a perpendicular relation.

De Geer Moraines Moraines at right angel to the ice flow direction End moraines belong to this class and they may either be large or small, short or long. (LiDAR) data, De Geer- moraines were mapped around eastern Norrbotten county, including Piteå, Boden and Luleå. A total of 14 651 De Geer-moraines were identified over the selected area.

The ridges may be up to 300 m apart and up to 15 m high. They consist typically of a till core, capped by a layer of partly rounded boulders. This landscape may have formed beneath the grounded part of an ice sheet that extended into a lake or sea. It is named after the Swedish geologist Baron Gerard de Geer (1858–1943).

Water generally tends to move vertically in moraine, whereas it travels Meneely, J. P., Chevallier, O. P., Graham, S., Greer, B., Green, B.

De Geer moraines (DGMs) were first identified in Sweden by Gerard De Geer in 1889 and have been mapped since then in many parts of Sweden. Using airborne Light Detection and Ranging (LiDAR) data, we have mapped DGMs over the entire country, and we show that they occur predominantly in two distinct areas: in south-central Sweden north of the Middle Swedish end-moraine zone and in northeast Sweden.

As we walk the 600-metre snow-covered hiking trail The major geomorphologic feature is the unusual ridged washboard moraines or “De Geer moraines” formed by the melting of the continental ice sheet. Several De Geer moraines are signs of the last ice age when an over two-kilometer thick ice sheet covered Kvarken Archipelago.

This is a wonderful LIDAR image of De Geer moraines in SW Finland. These stringy little moraines are generally assumed to form parallel to the retreating ice front -- but some way up-glacier from the ice edge -- in conditions where the bed material is saturated and where the ice is almost being lifted off the bed in a lake or marine environment.
