Which of the placemarks in the mass wasting landforms folder is the best example of a rock glacier?

The rock glaciers are most often found in cirque basins. They are distinctive geomorphological forms, consisting either of angular rock debris frozen in interstitial ice, former ''true'' glaciers overlain by a layer of taulus, or maybe something in between. This type of glaciers may extend outward and downslope from taulus cones, glaciers and terminal moraines of glaciers.
