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. De Geer moraine ridges occur in abundance in the coastal zone of northern Sweden, preferentially in areas with proglacial water depths in excess of 150 m at deglaciation.

In order to shed some light on the geochronological problem involved, the distances between successive ridges in a number of De Geer moraine series are also compared with clay varve data on deglaciation rates in Finland. De Geer moraine ridges occur in abundance in the coastal zone of northern Sweden, preferentially in areas with proglacial water depths in excess of 150 m at deglaciation. 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 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.

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 Marginal formation of De Geer moraines and their implications to the dynamics of grounding-line recession. / Lindén, Mattias; Möller, Per..

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 … 2014-08-26 De Geer- moraines found on topographic lows tend to have an interconnected concave form, while over or close to elevated areas; they’re slightly convex. The mean distance between prominent ridges showed a connection to the average retreat rate of the last ice, which suggests that prominent ridges had been formed annually. De Geer moraines almost certainly formed at a marine margin. Reaching altitudes of 55 m above present OD, these landforms may provide one of the highest geomorphological All De Geer moraines of any demarcated group of ridges were deposited almost simultaneously during a quiescent phase of ice flow, as the ice subsided into a water‑soaked subglacial layer of till. The basal crevasses, formed during the previous quick flow of the ice mass, were filled by material resembling ground moraine being squeezed up from both sides into the cavity.

Translation memories are created by human, but computer aligned, which might cause mistakes. During glacier recession, ice separation and intra-lobe ponding first led to subaquaeous deposition of sorted and unsorted facies. Subsequent glacier stabilisation and ice-marginal oscillation produced glaciotectonic structures in the ice-marginal sediment pile and formed De Geer moraines.
