talus

The bone of the ankle.

A sloping heap of fragments of rock lying at the foot of a precipice.

By the time he reached the first talus slides under the tall escarpments of the Pilares the dawn was not far to come.

Above here is what is known as a talus slope - sandstone that has gradually disintegrated and tumbled down to create a menacing sloping pile of loose rock.

The slope of an embankment wall, which is thicker at the bottom than at the top.
