moraines
Ice-deposited rubble heaps
Moraines are accumulations of rock, soil, and debris deposited by glaciers.
As glaciers advance and retreat, they scrape and carry material, leaving distinctive ridges and mounds when the ice melts.
Terminal moraines mark where a glacier stopped; lateral moraines form along its sides.
The hiking trail followed an old moraine above the valley.
