Thanks for the feedback re "glacier movement in one direction only" and confirming "definitely glacial polish" / "micro paste" Bass.
Any insight to add re the original question how such small scale/relatively tight curvature convolutions can be sanded/abraded by such large masses? I'm still having trouble picturing that process. Especially RD's photo example.
