North Facing Slope

    From the picture, one can notice that the slope is convex and it tilts upwards.  It has continuous vegetation of shortgrass native to the region, as well as wild rose bushes collected at the bottom of the slope.  They grow at the bottom to take advantage of the protection provided by the coulee from solar radiation.  Another reason for growing at the bottom is due fact that the moisture will collect at the bottom in the form of snow during the winter.

     A defining characteristic of the north facing slope is the presence of terracettes.  They are not formed by animals, but a complex geological process.

    Because the slope is convex tilting upward, there is more of a likelihood for the process of creep.  This is a slow process which involves the movement of the top layer of the regolith (layer of accumulated weathering products).  The top layer moves about 1 - 10 mm/yr down the slope, whereas the lower layers are more stable.  This process creates a stepped formation, shown in the above picture.
