At first glance, calling it a glacier might be technically correct, but don't think of a pile of pristine blue ice. Every glacier has a bunch of rocks in the ice, even the pretty ones. And there is a whole gradation of the rock / ice ratio from the nearly pure ice to the rock glacier. The rock glacier might have no more than ten or twenty percent ice - just enough to lift the clasts away from one another and start shearing on the ice to move. Below that, it'll still move, given a steep enough slope. But then it becomes talus, not a glacier in any sense.

My initial impression is towards the rocky end o' the spectrum of glaciology.
