Morphometric analyses indicate that moraines in the Seacoast region are on average 1.2 m tall, 885 m long, 30 m wide, and spaced 98 m apart. The results of this study indicate De Geer moraine formation in New Hampshire was likely driven by annual oscillations of the LIS margin in a tidewater setting.

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. De Geer Moraine Patterns of low profile, parallel ridges, sometimes referred to as "cross valley moraines", or "washboard moraine", but more generally known as "De Geer moraines", are present over vast areas, in Norway, Sweden, Finland, Maine, Alaska, NWT, Newfoundland, New Brunswick, Saskatchewan, Ontario, Quebec, and other regions; they also occur offshore on the Scotian Shelf. 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. Seen in lakes as narrow peninsulas, islands, and shoals spaced about 200 m apart, these narrow, parallel glacial ridges are called De Geer moraines, after the Swedish geologist who first deduced that the ridges mark the winter positions of glacier margins that retreated in contact with a water body.

The moraines occur in large groups at 40-300 m intervals, mostly in low-lying landscape areas. The Kvarken Archipelago has the highest numer of De Geer moraines and they occur in compact clusters. In the northern and eastern parts of the area 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.

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 m2, with considerable inter- and intrasite variability.

De Geer Moraine Map Symbol: MG First publication: 21 January 2021 Last modification: EtymologyThe De Geer moraines owe their name (Hoppe, 1959) to Baron Gerald Jacob De Geer (1858-1943), a pioneering geologist who was the first to observe these sedimentary structures in Sweden (De Geer, 1889). His work in geomorphology and geochronology had a major impact on the creation […] While De Geer moraines are widely recognized as products of ice recession in glaciomarine settings, their formative processes remain debated. Here, we integrate geospatial mapping, morphometric analyses, stratigraphic investigations and ground‐penetrating radar (GPR) subsurface profiling to characterize De Geer moraines in New Hampshire and assess their origin.
