Dola Posted July 8, 2017 Share Posted July 8, 2017 Found this on top of a limestone mountain at the continental divide in West Virginia. The next ridge over is where the coal starts. Link to comment Share on other sites More sharing options...
Ludwigia Posted July 8, 2017 Share Posted July 8, 2017 Looks like a concretion. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Dola Posted July 8, 2017 Author Share Posted July 8, 2017 In the second picture the spot is smooth as class. Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 8, 2017 Share Posted July 8, 2017 It looks like it may be Chert, or Flint, which is very glass-like in nature.

Dola Posted July 8, 2017 Author Share Posted July 8, 2017 Here is a picture of a spot that isn't glass like but is in the same shape. Link to comment Share on other sites More sharing options...

The color differences may be due to mineral staining. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Ludwigia Posted July 9, 2017 Share Posted July 9, 2017 The rest of the photos and your description of the hardness only serve to confirm that this is indeed a concretion, the centers of which are sometimes extremely hard. Just imagine superman pressing sediment together like a snowball. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
