Less pressure, which occurs closer to the glacial maximum, can cause ice to melt over the streamflow, resulting in steep-walled, sharply-arched tunnels. Such a stream may meander a little as it winds its way underneath the glacier, making its way to the front of the ice. Because of the weight of the overlying ice, the subglacial meltwater is under high pressure. Most are sinuous, with a height of a few to several tens of meters. As a result, by studying eskers, we can gain a better understanding of how glaciers and ice sheets respond to climate change. Eskers are more common on paleo-ice-sheet beds in areas of crystalline bedrock with thin surficial sediment coverings than in areas of thick deformable sediment.
