Morrisonite Jasper Polished Stone Slab
This lovely piece of Morrisonite Jasper is a stone slab polished on one side and is 4 inches by 2.9 inches and 9 mm or .38 of an inch thick.
The matrix areas did not take a polish.
Morrisonite Jasper comes from the famous Morrison Ranch area.
The Morrison Ranch is above the Owhyee Mountains of southeastern Oregon, in Malheur County near the Idaho border.
Morrisonite Jasper is a semiprecious gemstone material named after James Morrison, an old timer who lived in and explored the area for 50 years. Though the rock was first available in the early 1930's, it wasn't actually claimed until 1964.
Morrisonite is formed in Rhyolite seams and cracks and is confined to small areas, although the surrounding territory is of the same formation. There were 5 mines were Morrisonite came from, each claim yeilded very different colors and patterns.
The area is very rugged and the Morrisonite area is perched on the side of the hill. Mining was very difficult. The Morrisonite area has been closed by the BLM as it is too dangerous.
