The Muddy Creek locality is quite famous for producing exceptional septarian nodules (concretions), which start as rather ugly, generic potato-like rocks (last photo) until sawn open. Here we have a very fine example; the central hole is lined with sharp, brownish scalenohedral calcite crystals. The branching pattern radiating out from the central hole is appealing. What sets this particular example above others, however, is the roughly 5 cm long barite spray (third photo). Barite is quite uncommon in these specimens. The cut and polish is also excellent. Green fluorescence under longwave UV. An outstanding septarian nodule example, free of damage, and which displays very nicely!
