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. Comparisons of the measured variables of De De Geer Moraines 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 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. They consist typically of a till core, capped by a layer of partly rounded rocks. Features which can occur include hummocky moraine, high-relief forms up to about 10 m high, consisting of mounds, ridges and knobs, some doughnut-shaped; series of arcuate (bow-shaped) ridges of varying heights and lengths, named (according to their form, origin and position) cross-valley, ribbed, washboard, De Geer, push, ice-thrusted and recessional moraines; single, prominent ridges marking 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.

There may be several different origins of the crevasses. One possibility, proposed by Gerard De Geer who first studied these ridges, was seismic activity in connection with the isostatic rebound during the deglaciation.

Mo¨ller, 2005; Todd et al., 2007). Originally described by De Geer (1889), and named after him by Hoppe (1959), De Geer moraines are low ridges, typically510 m high, 10–100 m wide, and 100–1000 m long (Golledge & Phillips, in press). Aligned approximately transverse to ice ﬂow, these landforms form in subaqueous environ-

and De Geer type moraines, there are other ridges with more complex appearance that are not yet understood in terms of genesis. The category Ir - regular moraines include theses moraines and those that cannot be assigned to ice-marginal processes.
