Sedimentary, Glacial, Igneous, wind eroded...... I have no idea .... it could be a Meteorite for all I know [but its not because if it were it would be in a very big dent!].
Some things are beyond description, some things are mute because God never made words to encompass what they are, might be, were or could in time be......... some things just are “wonder”.
