This kind of landscape with many depressions with no natural drainage and isolated small hills is a typical dead ice landscape (Figure 17-3 and 17-4). It formed when the ice responsible for the MSL melted. The ice, which was partially covered by sediments, melted slowly and unevenly. This resulted in the isolation of lumps of dead ice that melted slowly. Clay, sand and gravel that were previously carried in the glacier or provided by meltwater were deposited between the lumps of dead ice. When the dead ice finally melted, small, often water-filled, depressions appeared where the dead ice had been – kettle holes - whereas the sediments deposited in hollows in the dead ice resulted in kames.
