eskertek
Eskertek is the Hungarian term used to refer to eskers, long, winding ridges of stratified sand and gravel that form in glacial environments. Eskers are deposited by subglacial or englacial meltwater streams flowing within or along the base of a glacier and become exposed after the ice retreats. They typically run parallel to the former ice flow and are characterized by sorted sediments, with coarser materials near the core and finer sands on the surface. Their relief relative to the surrounding terrain can range from a few meters to several tens of meters.
Formation: Eskers form when sediments carried by meltwater are deposited in channels within or beneath the
Distribution: Esker landforms occur in many regions that experienced extensive late Pleistocene glaciation, including parts of
Significance: Eskertek are important for groundwater storage, acting as conduits or reservoirs for subterranean water. They
