Rock glacier
Template:Classify Rock glaciers are distinctive and powerful geomorphological landforms of blocky detritus which extend outward and downslope from talus cones or from glaciers or the terminal moraines of glaciers. Enigmatic, their growth and formation is subject to some debate with two main theories in prominence. The first suggests that rock glaciers have formed from cirque glaciers and contain a glacial ice core powering the formation downslope. The second that interstitial ice between the rocks causes the formation to move downslope.
Ice glaciers differ from rock glaciers in that they are relatively free of debris.
