Septarian Nodule

I took pictures of the rocks at the airport. I think the one I like the best was the Septarian Nodule. They say it is found in southern Utah. 150 million years water covered parts of southern utah. Volcanic eruptions cause sea life and sediment to be trap in mud balls. The mud balls were then exposed to the sun when the water receded. This caused them to crack. Whenthe water returned dissolved sea life turned in calcite that settled into the cracks causing this type of formation. Rockhounds can find them in Kanab, Utah.

I love the contast in the stone.

The Picasso Marble can be found in this picture it is the small heart above, the black and brown bear shape on the back left, and the small bear shaped rock on the right.

The yellew rock in the middle is Honeycomb Calcite also found in Utah.
