The piteraq and williwaw forms of katabatic winds generally originate at these features. Deep holes that cut through these features are called moulins, and randklufts exist at the end of their corries, which also contain cracks called bergschrunds. Sheepbacks and kettle lakes are evidence for their former existence, as well as drumlins, eskers, and U-shaped valleys, which sometimes become fjords after these objects retreat. For 10 points, name these slow moving geological features that deposit moraines and are found in tidewater, continental, and alpine forms.
