Yet "Closer Up"

Flint, Quartz, Sedimentary
The closer I look, the more I can see the cracks.




I can start to see granularity, too!

Flint, Quartz, Sedimentary
I did not know it was made of granules until I saw these images.  I suppose I should have recognized the possibility when I read what Wikipedia said.  "It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones."  It is "categorized as a variety of chert."  I think that this rock may have come from Flint Ridge by Newark, OH.  It might be a scrap I bought from Pam Lauer.
