I’m actually surprised there isn’t Timelapse of it already. Seems like a simple enough setup to gather basically all of the information needed for finalizing how they move.

We have something similar where I live - no glaciers involved though, just river rocks.
The river dries up rapidly in the summer, leaving the smooth exposed bedrock riverbed peppered with rounded river rocks covered with drying algae.
Where the river is partially shaded, the rocks rapidly grow moss and other vegetation on their top surface. They preserve what little precipitation there is, and catch the morning dew. They grow top heavy, and fall over. They then repeat this on the next upwards facing surface. Meanwhile the downwards facing surface dries out from the radiant heat from the bedrock and shrivels into a thin black layer of desiccated biomass, which then partially falls off at the next rotation, further increasing the top-heaviness.
Over the course of a summer, the rocks all collect themselves into the local low-points of the river bed.
Then comes the flood and the cycle repeats.
