M.Chapman Posted June 19, 2018 Share Posted June 19, 2018 I took this photo of some scratch marks on some rock on Skye. This is a closeup. This is a more general view showing a similar scratched rock in the foreground. I suspect these scratches were caused by glacial action and have captioned an keyworded accordingly. But I would value a second opinion. I think it's quite unusual to see glacial scouring scratches in several directions. I suspect this rock (boulder) was originally inverted and being pushed along a rocky surface by a glacier above. The boulder may have rotated at some point causing the direction of scratches to change. That's my theory anyway... Thanks in advance Mark Link to comment Share on other sites More sharing options...
