(based on the Hell Creek Formation)
Description
Volcanic and hot, the plains of Hell Creek are poisoned by noxious fumes and the shadow of a rumbling mountain. In addition, a threat from beyond earth stalks the sky, ticking down the seconds until the end of the Cretaceous and the beginning of the Paleogene. Tar pits pose a danger to those seeking an easy drink and toxic rain from volcanic ash can poison fresh water sources.
Geography
Contained on the western portion of North America, separated from the rest via a great inland sea. A massive volcano stands to the north with a lush forest to the south with groups of lakes dotted in the green.
Features
Volcanic plains, highlands, forests, lakes and tar pits
Rock Type
Volcanic rock and mudstone
Fossilisation Extent
Found both around silty areas such as the lakes and the inland sea to the east.
