Large
block of Obsidian from Ft. Worth, TX Here is a view from the back
EX. Here is a picture of some smaller pieces note
the green one has some Olivine in it. **I
need to have this checked but I'm 99.9 % sure, but there really shouldn't
be any in this part of TX. I've got a picture of the location in the
Stratigraphy page.***

is a Felsite. A view of the rock opened up. Look at all the colors
