De Geer moraines (DGMs) were rst identi ed in Sweden by Gerard De Geer in 1889. 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.

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 Based on a total of 563 moraine ridges recorded in the present dataset from four primary study sites, De Geer moraines were found to be typically 50–300 m long, 10–20 m wide, 0.5–2 m high and individual ridges covering areas of 500–6000 m 2, with considerable inter- and intrasite variability.

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 The De Geer moraine or washboard moraine occur as a type of moraine landscape that consists of a series of separate, narrow ridges trending parallel to a former ice front, and which can form annually. The ridges may be up to 300 m apart and up to 15 m high.

Finnish De Geer moraines are thus neither annual nor end moraines. They are subglacial bedforms with no geochronological meaning, except that they formed during one single surge cycle. As the marginal zone of the ice sheet calved and thinned, it was lifted by proglacial water and the whole group of moraines became free of ice almost simultaneously.

Saltkaret kan besökas de Geer moraine A type of moraine landscape that consists of a series of separate, narrow ridges trending parallel to a former ice front, and which can form annually. 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. De Geer moraines are generally considered ridges that reflect a saccadic, annual retreat of a stable ice margin in contact with a water body. The formation of each ridge is thought to be the result of sediment accumulation in association with minor stagnation or recession in winter (Andrews and Smithson, 1966; Barnett and Holdsworth, 1984; Larsen et al.
