It’s all in the Name
Friends, these red rocks are called scoria in North Dakota, but they are also called clinker. They are very fragile and break into pieces when dropped or otherwise subjected to blunt force trauma. It is formed from layers of bentonite clay being baked by a burning coal vein hence it official name, porcelinite. The formation of a china cup in the badlands of North Dakota. til Tomorrow MJ

Their colours are beautiful. Was a road cut into this mountainside?
no road, just wind and water washing out the cut bank and dumping red rock into the stream below, thanks for your conversational comments, i love them
