The 5,600 islands of the Kvarken Archipelago feature unusual ridged washboard moraines, 'De Geer moraines', formed by the melting of the continental ice

(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. Six parameters were analysed during this study; length, orientation, steepness, distance between ridges, current ground level and depth below highest shoreline.

These formations are part of Kvarken-Höga Kusten UNESCO World Heritage area. De Geer-moränen har troligen formats i sprickor som gick parallellt med iskanten under vattenytan. Moränryggarna är ofta ett antal hundra meter långa och cirka 5 av H Möller · 1962 · Citerat av 24 — A preliminary report is given regarding investigations of De Geer moraines (the t e n introduced by Hoppe 1959).

At the posting coordinates you will find yourself on the edge of the road looking across a field that is showing a De Geer moraine. De Geer moraines - Earthcache (GC1TFWJ) was created by PetoKrisu on 3/15/2010. It's a Not chosen size geocache, with difficulty of 1.5, terrain of 2.5. It's located in Finland. 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. and De Geer type moraines, there are other ridges with more complex appearance that are not yet understood in terms of genesis.

en Geomorphologically unusual in being one of the best examples in the world of the long and narrow De Geer moraines, a rare formation shaped by the last Ice Age, Merenkurku’s bizarre topography is a product of the withdrawal of the icecap, submergence by the Baltic Sea and rapid isostatic uplift (about 9 mm per year) of the land in reaction to the disappearance of the ice.

This study presents a model for the genesis of moraines of this type in the Chapais area, Québec. The model is based mainly on facies and deformatin structures analysis, and geomorphological data. Well‐stratified glaciofluvial material is commonly found in the core of the moraines, whereas till or glacial De Geer moraines, near Ten Mile Lake, Newfoundland. A moraine perpendicular to the direction of ice flow , forming a low, relatively narrow ridge of water-sorted till; De Geer moraines are deposited in shallow bodies of water at a glacier snout.

These ice-flow transverse ridges, sometimes known as De Geer moraines (De Geer 1889), have modest heights and widths and variable lengths. De Geer’s original description of Swedish moraines with these characteristics invoked an annual cycle. Present use of ‘De Geer moraine’ refers to

Comparisons of the measured variables of De Geer moraines with their deposition environment suggest that the dimensional variables of ridges are less dependent on the depositional environment 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. Each ridge consists 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 2016-01-01 2021-04-08 1989-05-01 2000-06-01 Lindén, M. and Möller, P. 2005.

De Geer moraines are ridges up to 5 m high, 10-50 m wide, and in some cases 1000 m or more in length.
