Found under bridge less than 60 yrs old in Middle Tennessee. Stalactite is composed of Calcium Carbonate and reacts violently with Hydrochloric Acid. This is conclusive proof it is made of same material as cave Stalactites.
This stalagmite was found on the ground under the stalactite in previous picture. It is therefore less than 60 yrs old and a good reminder that what most cove guides tell you about how slowly these formations grow is mostly incorrect. Time doesn’t make stalactites or stalagmites, process does.
This shiny black leaf is a polystrate fossil as 1. the partly excavated fern fossil is lying flat along the strata and 2. The larger leaf is lying vertically on its side across the strata indicating that the strata did not form slowly one on top of the other but rapidly and more than one layer at a time. The polystrate leaf is from a giant tassel fern and is one more evidence that the world was once much more plant friendly that it has been since Noahs Flood.
Our Field Trip was to the top of the Cumberland Plateau shown here beside
the Sequatchie Valley
Many of the vertical trees stand above coal seams and protrude through hundreds
of layers which had to be formed in less time than the tree took to rot.

But it was not just tree stumps that were buried quickly – so were many ferns.
We excavated this one below – beautifully preserved – a sure sign of rapid burial.
Close up the stem is easily seen to curve through many layers.
Always remember when you excavate a fossil that you are the first person to see it since God saw it last. And ferns are easy to recognize in the rocks as they have done exactly what God said – produce their own kind. SEE THESE FOSSIL TREES ON OUR DVD DARWIN ON THE ROCKS- FREE PREVIEW
