#APicADay 2020: Day 60

Working around the house this morning while there was good weather, foul weather in the afternoon, and activities away from home this evening have kept me from doing anything until now.
Today's image:

Fuji X-T3 with XF 18-55 @ 55mm, f/20, 1/250 s, and ISO 160

I do not know what this rock is. I just like the difference in the polished surface and the raw surface you can see as you look at the left face versus the right face. There is also a bit of iridescence in the material that does not come across in a single image. You would need video to be able to see that.
