The steep hill is a truncated spur, Langhaugh Hill. Truncated spurs (aka "spurs") are features at the ends of artes where the rock is eroded into steep triangle-shaped cliffs by the glacier in the main valley. Continental glaciers form in a central location with ice moving outward in all directions. Continental Glaciers are much larger and cover huge area and Valley Glaciers are long, narrow and on top of high mountains. True. 7 What kind of rock has a truncated spur?
